Replace that cheesy stock seal that can never seem to keep the water and dirt out. At Quad Logic they developed an improved seal made out of silicone that rebounds and wont compress with time like the stock seal. The stock seal is a cheap foam that easily compresses and instantly loses it's shape. This allows a ton of dust and dirt into your airbox and ultimately your engine. This new silicone seal will always keep its shape so it will help eliminate water or dirt in to the air box. Installs just like the stock unit, no modifications necessary.
