K&N designed the 63 series aircharger to be larger and have even less resistance. They improved upon existing designs and came out with the aircharger, the biggest conical filter they could fit in the engine bay while maintaining the factory mounts.
Less Maintenance! Because of the larger filter size, cleaning is no longer required up to 100,000 miles!
Durability. K&N use high quality materials to give you a durable product that is sure to last. The intake tube is made from interlaced high density Polyethylene, while other parts are made from reinforced nylon and silicone.
K&N guarantee a difference in HP and acceleration. Mounts easily using the factory mounting locations. Comes with a one million mile limited warranty! Works with OE computer systems and is street legal in most states.
**Not street legal in California**
