Description

This Performance Air Intake System allows your engine to breath more air compared to the restrictive factory air intake housing. It is designed, tuned, and dyno-tested to produce more horsepower and torque. The cone-shaped AEM Dryflow air filter is made from an oil-free, synthetic filter media that can be used for up to 100,000 miles before cleaning is needed (depending on driving conditions). A custom shaped heat shield with edge trim lining is included to keep engine bay heat from the air intake. The air intake tube is constructed from mandrel-bent aluminum featuring a durable gunmetal gray powder coated finish. This air intake system is backed by AEM's Lifetime Limited Warranty. Some AEM air intakes are not legal for sale or use in California and other states adopting California emission standards, while others are 50 state legal. View the vehicle applications to determine the legal status for each vehicle.

Worth it
Easy to install about 2 hours. Be careful with the nipple piece it broke when I put it on so I had to go to act hardware to get a brass fitting but it worked perfect. Sounds sooooo good!

Uses stock airbox - this is a real CAI
This intake utilizes the factory inlet for the CAI, meaning it pulls air directly into the CAI in the same manner as the stock intake. Meaning this is actually a true CAI by engineering standards. Keeps the engine cooler than the original intake except under load. Power loss is noticeable on the high end but the sound makes up for it, a camry isn’t a racecar anyway. ... show more

2021 TRD Avalon CAI
Was easy to install , only issue was that one plastic piece that threads into the bottom, it will strip out real easy. Ended up going to Lowe’s and finding a metal want to replace the plastic one threaded in. Other than that, I noticed the difference. Sounds good.

Great product
I've purchased many aftermarket upgrade kits of varying varieties over the years for everything from cars trucks motorcycles and guns and this one surprised me. I always expect to find some aspect of the kit that doesn't fit quite right or mediocre to low quality but that wasn't the case with this product. Everything was perfect. It's also rated at 14 hp but that's at 4500 rpms. My car revs higher now and pulls a little harder. I'll guess peek hp is closer 18 @ 6500. ... show more

Sound and Performance
This is a great intake, it brings life to the car in terms of sound. At 3000 RPM+ you’ll hear a difference but only at heavy throttle. In terms of performance, there is a difference especially at higher temps. At anything above 75 degrees, the car wouldn’t feel as powerful but now it’s not as bad. The price may be a little steep but it’s worth it to me. I got it on sale for 400. ... show more

Don't waste your time. Bad quality and damaged.
Paid +$450 for a "new" intake and I received a damaged intake that is scratched, possibly defective inside the pipe, and has rust. Returning and going with a different brand, this is a waste of time, save yourself the time and go elsewhere.
