About this item

  • Estimated horsepower gain of 8.4 HP at 7300 RPM
  • All AEM Air Intakes come with a lifetime DRYFLOW Synthetic air filter with great filtration
  • Manufactured in the USA


AEM Air Intake Systems are designed to produce massive horsepower and torque gains as well as better engine sound when used as a replacement for the factory airbox and air filter. AEM intake systems are designed, tuned, and dyno-tested to fit specific cars and trucks. These air intakes usually include an oversized AEM Dryflow synthetic washable air filter for outstanding air flow, filtration, and performance while allowing easy oil-free cleaning. Most AEM intake systems use mandrel-bent aluminum intake tubes, powder coated heat shields, and high quality hardware designed to reduce restriction and reduce intake temperature. The design and components of each intake system vary so consult the installation instructions for more information on the contents of each part number. AEM manufactures a variety of intake kit styles including short ram intakes, cold air intakes, dual-chamber intakes, Brute Force intakes for trucks and SUV's, and Brute Force HD intakes for diesel applications.

Fits the rx8 nicely.

My original intake had become brittle and parts were cracking off, purchased this one and it works well. Note, you will need to cap off a vacuum port on the upper plastic intake manifold on the driver-under side just past the throttle body, it’s the secondary air injection port. Car ‘might’ run a little funny for a short time after install, but the computer gets it figured out fairly quickly. Car runs great, would recommend

An amazing piece to buy if you have troubles with your rx8 idling really low this can be a huge difference to the car it has a really mean sound to it that'll definitively put a smile on your face and is quite easy to install the red is brighter than expected but it does work out well for the car (some pieces do not go the way it was packaged it could give you some head scratching if you think it is that way)

Well worth it for the price. I'd gone back and forth for a while on whether or not to get it. Finally I did order it (Amazon had it the cheapest with free shipping). Install was a little sketchy. The instructions arent the clearest and I was guessing on some parts. In fact when it comes to the clamps and hoses (rubber connectors) it doesn't really tell you which to use, so I put it together wrong. Lol. Luckily I was able to change it without pulling everything back apart.Performance wise,throttle response is better. As far as sound, I run a straight pipe from the cat, so I can't hear if it sounds differently or not in the cab, but in the engine bay at idle is has a cleaner sound.Had to argue with myself whether or not to give it 4 stars for the instructions, but it's too great of a product to knock it down that far over paperwork. AEM claims ~8HP gains at about 7800 rpms, I saw about 6.5-7 on average, which is still not bad for this car.

Was hessitant to buy for awhile considering the price. But i have to say it was worth the purchase. Product is very well made and easy to install. The hardest part was taking the front bumper and metal bumper off to fit the piping. Install took me about 2 1/2 hours but could be done quicker. Sounds pretty good throughout the RPM's but really impressive 7-9. Also comes with dry wrap for the filter which is a nice add. The only Con I can think of is the price/time it takes to install. But as you probably already know, anything with this car is a little more money. Overall I give it a 5 star because its very well made and a nice add without to much trouble.

Great product. Sounds amazing. Gives my rx8 an aggressive growl. Looks fantastic in the engine bay. Easy to install though the instructions are not good. It's pretty straight forward to install.

This is a great looking setup once installed. The largest part of the job is to remove the front bumper. The install took about 4 hours.The intake sound is deep and throaty at high revs (6000 rpm +). Not too loud. It feels like it should be complemented with an after market cat back.
