This intake has dual stainless steel funnels to direct intake air smoothly into the throttle body. The air filter is made of an unrestricted race quality element and has one funnel at the top of the filter and one funnel at the base. Apex engineers noticed in tests that when the vehicle sucked in air from the side, an area of wind turbulence occurs in the middle of the filter. To cure this problem, a funnel at the top of the filter was added to channel the air down to the base of the filter. A separate funnel at the base of the filter ensured the smooth transition of air form the atmosphere into the intake pipe. Both funnels are constructed of a high quality polished SUS 304 stainless steel and the craftsmanship only found in Apex products.
The part installed very very easily. I was able to order the specific part for my vehicle as the model of my car was never made in North America. I haven't been able to road test it with the intake installed but while it's running, you can definitely hear it suck in more air, the turbo's spool very easily, the spooling is more audible as well as the stock BOV. Top notch product, came with everything necessary.

Fits great, easy installation, great quality, good flow and excellent filtration, expensive replacement filters keep me from rating it higher.

By most accounts this is the best air filter/intake for the mk3 supra. Easy installation. Fits right up to the stock afm.
Don't expect to see a huge horsepower gain from this one mod. What you will get though is a little more noise from the engine, and you can hear the stock blow off valve. Also this is the first step for letting the car breathe better.
A must for anyone wanting to get more HP out of their Supra.

Had a little fitment problem, but made it work. Overall the Intake work very well.

The installation was easy, even though the instructions were in Japanese and the diagrams we hand drawn. It came with all the accessories you needed to complete the installation. Fitment was excellent and the product was very well made. None of the brackets looked cheap or bent easily, the VAF adapter was cast aluminum, and the filter was held tightly to the adapter. After installation, a noticeable gain in the low end (specifically low rpm street takeoffs) where the car used to bog a little before, and a subtle growl from the intake after the aux ports open up in the midrange.

This intake is great. First of all i wanna thank HPF for the fast delivery and the awesome service. This part was installed in less than 30 minutes. Apex could have done a better job with the instructions but over all i think it was easy. a bit faster spool up and a bit more power felt after the installation. i have no complains with this product. Thank you HPF.

excellent fit, sounds good, turbo spools faster. Only possible issue is that the instructions are in japanese only, but it has sufficient diagrams.
