Review on Uni Filter NU 4109ST 2 Stage Air by Matt Chirila

Revainrating 5 out of 5

Good price UNI filter

I have used UNI filters for many years and find them better than expensive K&N filters. Revain had the cheapest price back then, even cheaper than ebay. I originally tried to buy some NOS UNIs on ebay for about $15 each but after I bought them the seller couldn't find them. This was the next best price.

Pros
  • Pack quantity: 1
Cons
  • Long delivery time
