Product Reviews      Review part E-3340

 I wanted to retrofit a modern air filter onto an 81 year old air cleaner that is an odd size by today's standards. I looked on several manufacturers' websites but none of them had a listing of their products by size - they were all application-driven. Only K&N had a lookup tool that lists what they have based on the size you enter in a tool. As it turned out they make a filter that was exactly the size I needed. They shipped it within 24 hours, it fits perfectly and there are no signs of restrictions in the air flow to the carburetor.

 I ordered this to use in a special carb scoop that mimics the old hilborn injection type look and its going on my 1930 Ford coupe with a 580 hp small block Chevy. The workmanship and quality of the filter is great, and just what i expect from K&N and have used your products on many applications for years. Thanks
