K&N RX-4750 Universal X-Stream Clamp-On Air Filter Product Reviews

Wednesday, May 24, 2017 - Part RX-4750
I bought this filter looking for the largest one I could fit with a 3 flange. It turned out the filter was for a Nissan Xterra intake kit. The flange is 3, but the opening is much smaller. It also has a hole in the base for an intake air temp. sensor. I wish there was more info and pictures as I had to exchange the filter, but K&N live chat was very helpful.

Excellent solution for creating more room under the hood and still providing outstanding performance for my 1962 Willys Pickup with 231 V6.
