K&N 57i Series induction kits are specifically designed for each different vehicle and will free your car from the size restriction that comes with the factory air box. These economical kits can take a variety of different forms based on vehicle characteristics and available space under the hood. Each kit is designed to provide power throughout the RPM range. The extra surface area of these open-air air filters provides even more airflow at lower restriction than a K&N O/E replacement filter which is limited to the size of the factory air box. The larger air filter also captures and holds more dirt increasing its service life before a cleaning is required (up to 100,000 miles). The filter is either directly attached to the engine carburetor or throttle body or indirectly through a tube assembly running from the filter to the engine. All adapters are made from high quality materials such as steel, aluminum, silicon or reinforced nylon to ensure long life. 57i Series Intakes are not legal for use in California and other US States adopting California emission standards.- Guaranteed to increase horsepower

Good deal for the price
Style: 80 mil 18 SqFt
The product is good and contrary to some comments I read it was not a mess to install and went on very nicely. That said I placed on a 71 Baracudda and starting from a 71db I was able to drop that down to about 66 with two layers Kilmatt 80mil

Excellent Sound Deadening Material!
Style: 10 SqFt, Style: 10 SqFt
I installed Kilmat Sound Deadening in my truck, and I’m extremely impressed with the results. The material is thick, pliable, and easy to cut to fit doors, floor panels. It sticks very well to metal surfaces and doesn’t peel, even after heating it slightly to make it more flexible. After installation, I immediately noticed a reduction in road noise and vibrations. Worth the money!!

A Must Have For Car Restorations!
Style: 80 mil 36 sqft, Style: 80 mil 36 sqft
I have been installing this matting in my 74 Datsun 260Z restore and very pleased with the ease of application and overall quality. My car has bedliner coating inside and this stuff sticks extremely well and is easy to trim and shape as well. I have just started installing it and using the rollers to work it in place but I can already tell a difference with just the little bit I have added....has reduced the resonance in the metal already. It's not a fast process but know it will be very rewarding once complete.

Great sound mat for the price!
Style: 50 mil 50 SqFt, Style: 50 mil 50 SqFt
This is a good product. Many people go with KILMAT because of the value to price point. I did as well. When you clean the surface (in my case it was all painted metal) this stuff sticks very well. I do recommend you use a seam roller of some type, I used Lumiteco 3 piece roller set. This will help with adhesion and mostly flatten the overlapped edges. It also helps you see where you have rolled as it leaves little grooves. The difference when we had no sound mats and after was very impressive. We haven't finished our install yet and it is quieter than when we had an interior in the van. There are thicker mats available in other brands, but this will work great for our van build, but this helps keep the weight down. It is quality material, just be careful when you are removing the backing, the edge of the foil face can cut you. I suggest you layout where you are installing the mat and cut to fit. From what I have read, you don't need to cover every inch in the vehicle, just spot install for a big difference. I chose to cover most surfaces to help keep sound out when we are sleeping in the van. We haven't finished putting the van yet, but we have driven it around and been very satisfied with this product.
