AEM 21-792C Cold Air Intake System, (Carb Compliant)

The media could not be loaded.  Took some time as I thought, it feels solid, sounds really good, time will tell the gains but I love it so far, also, keep in mind you may need to buy a larger hose clamp since one of the clamps did not fit over the filter inlet,*edit 9/19/23Removed the SRI since I saw my mpg go down from mid 30s to mid 20s, but it is not really AEM’s doing, just the matter of modifying the flow of air, for now, I will be putting my factory air box back in and putting a DryFlow drop in filter in, only knocks a star off, don’t let it steer you away, it’s a good intake,Little thing I noticed, it’s only really loud when I put my car in sport mode, in drive it’s only a bit louder than stock, I like that though, makes it easier to be quiet when I want to,All in all, great filter kit, would recommend,I feel as if the dry flow filter will prove to be more reliable than the oiled filters,

Delivery was fast, comes with instructions. It was pretty easy to install. There are videos online too. Looks really nice. Only issue I ran into was I had to make a bracket for the Top/left side the holes were way off. But it did say it did not fit my year. I took the chance and so far glad I did. The bracket was also pretty easy to make.

Worked perfect for my 2017 Honda Civic Ex. Made the engine sound like a growl and a tiny bit better throttle response. Very good for something you just bolt on!!

Car: 2017 Honda CivicEngine: 2.0L K20C2TL;DR: Great quality product, have used it for over a year and installation was straightforward; Affordable upgrade for better driveability and sound, minimal HP gains, maintains fuel efficiency, and is a durable CAI with no issues; CARB legal in California (EO: D-670-26) but not shippable via Amazon.Installation:I purchased and installed the AEM 21-792C Cold Air Intake in April 2023. The installation process was pretty straightforward as the kit came with an instructions manual. The main difficulty was removing the factory airbox as some of the screws were stripped and had to be taken out with other methods, especially with the MAF sensor. I had to do a transmission fluid change at the same time, so it was rather convenient. The AEM CAI is a tight fit, but I didn’t have any major difficulties in installing it. It took around 1.5 hours to fully complete the installation.Performance:Do not expect huge horsepower gains as most CAIs have very marginal improvements to overall HP. According to AEM, there is an increase of ~5-7 HP, which equates to about a 3.1%-4.4% gain in power. You will notice a slight increase in throttle response, which does make the car feel more responsive. Another benefit is the deeper intake noise and the enhanced sound, which might be worth it if you want a more aggressive sound.Durability:After 1 year of use, I’ve inspected the CAI consistently and can confirm that the parts are of great quality. Besides minimal wear and tear, there are no issues or damaged areas and the CAI has held up very well. The only addition I made was installing the Air Filter Wrap, which protects the exposed filter from water and larger particles. Not entirely necessary, but it gives me some ease of mind. There is a limited lifetime warranty, so do keep that in mind.Value and Worth:The CAI is a relatively affordable modification compared to other aftermarket modifications for the car. If you appreciate the auditory and visual enhancement, then you might consider the investment to be worthwhile. The HP gains are minimal, but there are noticeable improvements in driveability and engagement. My MPG has not changed much as I still get ~28-30 MPG (city & highway combined), but that heavily depends on your driving style. I would not purchase this if your car still has a warranty, as it will void it, so be sure to consider your options.Final Thoughts:I thoroughly enjoy the AEM CAI, and definitely felt it was worth it for me. CAIs are not meant to drastically increase performance, especially with a naturally aspirated engine like ours. But, it is a great entry-level upgrade that offers improvements to my driving experience and a chance to learn more about the vehicle.This is more like a “future-proofing” modification, especially if you are interested in adding additional aftermarket parts. Honestly, if you just want a little more sound without the hassle, just get a drop-in filter the next time you have to change your air filter (which is considerably more affordable). Otherwise, the AEM CAI is a great option if the price is right and you feel like it’s worth the upgrade.**Note for California Buyers:The AEM CAI is CARB legal in California, the EO number is: D-670-26. Be sure to install the CARB EO sticker onto your CAI in order to pass your smog inspections.As for shipping, Amazon does not ship CAIs to California due to the CARB restrictions. I spoke to both an AEM and an Amazon Representative, who confirmed that the CAI is CARB legal, but the seller (Amazon) restricts shipping due to legal complications - even if it is CARB legal. You can either: 1) Purchase directly from the AEM website or 2) Have the CAI delivered to another valid shipping address and have it delivered to you. You might consider these options depending on the price point or discounts.

Bought just yesterday & installed today. Love this product for my Honda-Ex so far. Sounds amazing. Took about an hour to install properly. Definitely would recommend.

Easy to install definitely worth the money

Easy to install, sounds great. Gas mileage seems to be about the same if not a little bit better! Love AEM products!

Easy to install and works great with 2021 Honda Civic.

Suena muy bien, si hay una diferencia de respuesta en el vehículo, obviamente si quieres algo más notorio, debes reprogramar la computadora para que así trabaje mejor. Si hay un cambio en cuanto al consumo de combustible, pero, es lógico, a mayor aire y potencia, mayor consumo de combustible. Aclaro, no es exagerado el consumo. 100% recomendable.

Nice product, relatively easy install, cleans up your engine bay and adds flare to it, you can feel the car breath better and adds acceleration response and nice sound, would recommend to any civi owner
