Product Description
Our Stage 1 Performance Kit is very popular and includes a K&N style high flow air filter, aluminum air filter adapter, and an upgraded drilled main jet for the carburetor. This kit is a simple but very effective upgrade over the stock air box. This kit needs to be paired with an aftermarket header for it to work properly. With the added air flow, the more rich main jet is mandatory for optimal engine performance. Filter inlet measures 2 7/16" ID and 2 7/8" OD. Includes choke hold bracket as well.

Adapter and air filter fit nice, but the choke hold Down tab did not line up at all. Had to bend it around quite a bit and it still doesn’t fit exactly right. Also I did not receive my pre filter with my order, I emailed the company a few days ago and have gotten limited responses. Still waiting to hear back about getting the pre filter.
