The AEM 21-508R 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 driver-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 red powder coated finish. This air intake system was developed to accommodate the engine's factory emissions control devices including the inlet air temperature sensor and a replacement breather hose. 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.

Not left stranded anymore!
Color: Vivid Orange
I bought two of these tire repair kits to put one in each vehicle. I also bought two new jacks for each vehicle. Generally them jacks that come with your vehicle aren’t no good anyways. I had a flat tire way out in the country and I couldn’t get my tire off, with that cheap wrench. I couldn’t get the car jacked up anyways. left me stranded. Not anymore I got two new four-way lug wrenches two new jacks and a tire, patch kit, and two of them little air compressors that you hook up to your cigarette lighter..

Amazon sell a fine selection of replacement fiberized rubber fiber plugs & cement. Read the reviews.
Color: Vivid Orange
This is the only kit you will ever need at roadside to plug a tire & be on your way.
This kit has it all. I'm a retired long haul trucker. This is my preferred plug kit. I have
stored one of these in all of my trucks & my wife's SUV. You could spend so much
more for other plug kits. But this one works. The price reflects the quality of both
the tools & all the other essentials you will ever need. I recommend you buy this one.
The money you save can be used elsewhere.
Note: Amazon sell a fine selection of replacement fiberized rubber plugs & rubber
cement. This is where you don't want to skimp on cheap-O plugs elsewhere.
These two items are the most important items in the entire system. Be prepared!
Always read the reviews & know the sellers reputation before you purchase things.
