AEM IND Cold Air Intakes

Engine Cold Air Intake Performance Kit

The AEM 21-417P Performance Cold Air Intake System produces horsepower and torque gains by replacing your vehicle's restrictive factory air filter and air intake housing. This air intake system was designed, tuned and dyno-tested to fit specific Honda Civic SI models. Air enters the system through an oversized AEM Dryflow synthetic washable air filter for outstanding air flow, filtration and performance. The air filter is relocated to the passenger-side wheel well which is designed to reduce intake air temperature and increase horsepower. The intake tubing is constructed from mandrel-bent aluminum featuring a durable chrome-like finish. This air intake system was developed to accommodate the engine's factory emissions control devices including the engine breather hose and inlet air temperature sensor. The tapered cylinder 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). The 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 21-417P vehicle applications to determine the legal status for each vehicle.

AEM's Performance Cold Air Intake Systems are designed, tuned and dyno-tested to give your engine more power and acceleration by replacing the restrictive factory air filter, air intake tubing and air box assembly.

Perfect
Size: 9.25”, Color: black-4 pack, Size: 9.25”, Color: black-4 pack
very nice brackets..very sturdy. Fits a 1x10 board perfect. Comes with everything you need and a.cool little level also. I loved them.so much I bought another pack and decided to add more shelves for my plants. It was easier to mount the shelf to the bracket then mount the whole shelf. Holds almost all my plants some are pretty heavy.

Well made brackets
Size: 11.25“, Color: black-6 pack, Size: 11.25“, Color: black-6 pack
These are nicely manufactured in that they are all exactly the same (with no variations) and with nice countersunk holes for the provided black flat head wood screws. I used a stained 1x12 #2 whitewood (Eastern Pine) from Lowes for the shelves. With these brackets solidly installed into wall studs at 32" on center (every other stud) the 1x12 shelf will easily support a heavy book load. I like the look better than the brackets that have the vertical leg below the shelf. It looks a lot cleaner. It is probably inevitable that your stud layout will result in a bracket or two needing to be installed between solid wood studs. In this case, do NOT use the sheetrock wall anchors provided with the brackets as they will pull out of the wall under an appreciable load. Instead, get some "Snaptoggle" toggle bolts and replace the provided bolts with #10-24 x 1.25" flat head machine screws in black. These toggle bolts are incredibly strong and easy to install. I am adding a postscript to my review regarding bracket spacing recommendations. With a heavy book load, the 1x12 shelf boards don't sag with the brackets spaced 32" apart, however I have found that the brackets themselves are overstressed by about 30% (they are only rated at 80# each.) Heavy books weigh up to about 36# per lineal foot so the maximum spacing of the brackets should be 24" apart. At 32" apart, they won't pull out of the wall if they are fastened into studs but they will sag a little bit back to front under this load. So I added additional brackets in between the installed brackets and now they are 16" apart at the heavy book shelf. The load on each bracket is now less than 50# but they STILL sag about 3/16" from back to front when loaded with books! No danger of structural failure and the sag is not really noticeable.

Very sturdy and all hardware needed
Size: 9.25”, Color: black-12 pack
These brackets are very sturdy and came with all the hardware needed, including two types of wall anchors if you won’t be going through a stud, and a magnetic level which was very useful. Would recommend.
