Comprised of multiple embossed layers of stainless steel with the outer layers utilizing a Viton rubber coating. Compressed thickness is 0.040". 4 Bolts in Valley. Cometic MLS (Multi-Layer Steel) Head Gaskets provide maximum sealing performance for todays high output engines and require no sealants. MLS gaskets are ideal for both aluminum heads to aluminum blocks and aluminum heads to cast iron blocks. They can withstand the shearing force created by the two materials. MLS gaskets have increased strength because they are comprised of multiple layers of stainless steel; which also creates the ability to rebound and resist corrosion. The outer layers are embossed and coated on both sides with Viton (a flour elastomer rubber based material that is heat resistant to 250 C/ 482 F). Viton is designed to meet the demands of a variety of harsh sealing environments, load conditions, and surface finishes. The center or shim layer is uncoated stainless steel, which can be varied to accommodate multiple thickness requirements.

Better Than OEM – Worth the Upgrade
Size: 1" x 1" x 1"
The K&N filter is a big step up from the standard Toyota air filters and OEM replacements. Installation was quick and easy, and the fit is perfect. I’ve noticed smoother airflow and better throttle response compared to the stock filter. The best part is that it’s washable and reusable, so it’s a long-term investment instead of constantly buying replacements. Definitely a smarter choice for anyone who wants performance and value over the typical paper filters.

Does the job, economical and a perfect fit
Size: 1" x 1" x 1"
Bought exactly 1 year ago for 3rd Gen Tundra. So far, it really does the job. At first I didn’t realize how awesome it was until I had to remove and clean it yesterday. Although I keep my truck immaculate inside and out, after 1 years use, the filter had become extremely filthy and the air had an old mildew, vomit, stank smell. When clean and set for fresh air, I can only faintly notice diesel exhaust smells from those in front of me. I also notice little to no dust accumulation on my dash and flat surfaces. In my opinion the K&N cabin filter kit is an essential tool for cleaning this filter. K&N made the filter, so I would imagine that they know how to clean and refresh it properly. By the way, refresh solution is nearly fragrance free. I bought the refresh kit at a big box auto supply and it came in a mostly black box instead of the white box as sold on here. Don’t know if that means the formulation has changed or not.
