Just wanted to say thanks for the service we received this summer. We were able to order parts and get them overnight. We were very happy with our service. I am very happy with the service that Ron Wyman gave to us. I will recommend your company to others. We only race small cars but we have 5 and when you need parts you hate to wait and we didnít have to wait, because Ron made every effort to get these parts to us as quick as possible. Thanks again Horsepower. And thanks Ron

the intake manifold was for my car(95 eclipse) but some modifications had to be made to it to work properly due to the vaccume lines in the back were the wrong size so i redrilled and tapped them no spot for the air fuel mixture relay so i hade to dill a hole and weld a piece of aluminum to the side for that and had it repainted there was also no spot for the hard line for the egr vaule so a hole and new line fixed that problem other than that it was super easy to install hp improvements were noticable if any one buys one i suggest a bigger fuel rail,injectors,and a bigger throttle body which i have all of and that makes a big difference

No problems what so ever and as far as cams go this is the biggest you can find duration wise for a miata. Unless you get Toda to custom make one for twice the price and wait a month and half for it to be made and then get through customs just to find out that they made the exhuast one instead of the intake like I did. So be smart order this one because everyone at horsepowerfreaks.com speaks English and they can have it to you the following day

Sound great, a little droney ~1500-2500RPM, but at crusing speeds is barely audible. Sounds great at WOT!! Quality is there, only thing is I wish it included hanger like the Carbon Ti. When the muffler was installed the shop had to weld on the actual muffler, looks bad IMO. Only other complaint is the tip actually has that rainbowy color.

It was a great product was not on my car very long because I went Turbo. But when it was on the car it was a great product except for the fitment issues of it rattling.

had problems trying to buy this piping from another vendor. 3 Months later i ordered it from here, and had it a few days later. Greddy Universal 60mm piping kit is very nice quality. Came with 2 cast aluminum bends, one with the word trust on it, and a lot of manderal bent pieces. More then enough piping to do my car.

Installation went without much difficulty. Be wary of the warning on HPFreaks website: "Installation Kit Required on Some Applications, see Install Kit Listing". This part does not come with neccessary hardware (nuts/bolts) to complete installation. Random's website should be consulted before determining whether additional hardware is required. (HPFreaks can't you make this easier for your customer?) Performance improvements were immediately noticable. Previously my car would pull until about 5000 RPM then level off. Now the engine revs freely all the way to redline with a noticable increase in HP. The car passed a recent SMOG test, however the results of the test were a bit concerning. On the 15mph test @ 2777 RPM the car put out 738ppm NO emissions. However the 25mph test @ 2646 the car put out only 50ppm NO emissions. I suspect the fact that the tester stalled the engine just before the test may have affected the results. The exhaust now sounds a bit more tinny than before, especially when cold. However once it warms up the tin sound seems to subside. My chihuahua (lots of bark, little bite) has never been happier.

It works fine but intermitten check engine light still exists despite changing scale parameters and checking and re-doing wiring harness several times and having 2 performance shops checking my work

the plugs work great, 15-20 minutes to install, seemed to be a little more responsive. Good quality product, for the price they are the only plug i will use from here on out.

I use to have misfiring issue's and wouldn't get a TACH signal when dyno tuning on a wide band with the stock 7MGTE wires. It was when I purchased Magnacore my problems were sloved. It's direct fit and looks great too. I highly recommend this to anyone who drive's a MK3/7MGTE

The perfect addition to my DX Civic that didn't have a factory tachometer. It was very easy to install since I did some research on how to install it through some forums. I found that you can attach the tachometer wire to the blue wire in the back of the guage cluster so there wasn't any unecessary excessive wiring needed through the firewall. Switched power and all other wiring was also done through splicing into the factory guage cluster. It was the perfect size for what I needed because I don't like those 5 inch ones, very clean and the white guage face topped it off. It was also very easy on the wallet as far as pricing.

Im very pleased with this product. I originally purchased a Centerforce clutch and had numerous problems with slipping and not engaging when hot. I then bought a Spec clutch and havent had a problem yet. It has great holding capabilities and never fades. I since blew my engine, I will be turbocharging and complete internal work will be done. Im confident the Clutch will handle 400+ hp and if it deosnt, ill purchase the next stage up in Spec clutches to handle the power. Im also completely satisfied with the ordering process and speady delivery I received.

A wonderful clutch and very suprisingly streetable. It grabs hard yet has the weight of a stock clutch.

I was hoping for the black chrome version and was a little disappointed after hearing it was discontinued, but the brushed version responds very well to powdercoating. All in all, I'm very satisfied with the gas cap.

Instalation on this product was pretty easy, the tasks that took the longest were related to the make of car that it was used upon. After insaling the air intake an increase in horsepower was noticed. Overall this product does very well.

This product performs as expected and I highly recomend it for anybody looking to have a high horsepower machine. Tuning and knowing your A/F ratio is very important in proper tuning for any car weather it be stock or modified.

Install is not very hard at all but is very time comsuming if you are just jumping in head first(not really knowing what you are doing) The only set back for me was unbolting the exhast to get to the stock shifer because the bolts are a bit hard to loosen.

My screening behind the carved letters has already fallen out so it must be reglued. Also I had a lot of residue on the letters and on the steel that I had to remove. This resulted in micro scratches in the areas that were affected. Other then that it was great-easy install and great fitment and shiny as a mirror.

Steve Kalesia

Very good quality product and great construction. I wish their was a boot to keep dirt out of the seals though on the shock. Easy to adjust and they lock in place well. Also lighter then stock and handling was greatly improved.

Only draw back was having to fab up my own brackets. Would be nice if someone would design a kit with brackets and fittings. Other then that it works great and keeps the fluid cool. Good product.

Easy bolt on modification. My stocker was clogged so I went with arguably the best aftermarket out there for the Supra TT. All bracketry and shroud fitment was great and the car seems to be running cooler in the summer heat. I am a happy camper.

probably the singlemost coolest add-on Ive purchased! love the loud blow off noise it makes! Gets all the attention!

The pump was very powerful while it worked. It experienced failure after a matter of weeks. The people at Walbro said it was because of contamination. Indeed, the inside of the fuel strainer was filled with sludge, streaming right to the pump's intake. I have decided to stick with OEM stock pump, which has worked wonderfully from the time I replaced it. This has altered my plans somewhat for my DIY turbo project on my Miata.

Instant performance at your doorstep. It was very easy to install, and I noticed top end power increase on the freeway.

No doubt a nice product, adding both to brake system performance and appearance. Only one minor complaint; that the stock pieces had a piece on the caliper end which prevented improper rotation of the brake line during tightening of the banjo fitting. This was a minor issue and is not expected to reduce performance but would be nice to address and correct.

custom install, easy too. pointless to get if you donot have a wideband O2 sensor. great product, the girls love it, but basically just a light show

Ray Brooks

-----------------------------------
I like the AEM wideband except, the range I feel should be slightly larger (ex. 10.0-20.0). The calculation rate is extremely fast and responsive. The display is easy to read at a glance, and good looking as well.

The product itself is fine but is to "Generalised" in it's purpose. Not all GM V8 cars have the same motors or oil pan locations. This was ordered to move oil filter location on a 1998 Trans Am. Given the low ride height of these cars the tubing included does not allow for location to the engine compartment where depth and ground clearence would not be an issue. If this was installed in a location where the hoses would reach it would be on the bottom of the car and very susceptable to being ripped off by speed bumps or any high road points. Unless I get 90 degree elboe joints so lines won't kink and have longer hoses made to allow for location into the engine compartment, this kit will not work for oil filter relocation on my 1998 Trans Am. It would be nice also to see a more high performance version of this kit which includes braided hoses to protect more from abrasion and heat as the hoses can run close to the exhaust headers. Again, the kit itself seems alright but is not really a good solution "As is" for oil filter relocation on late model Camaro's and Trans Am's.

tested the spring for tention and coil bind and they test a bit stiffer than stock, but coil bind faster than stock ones. not recomended for high lift cams.
