K&N RX-3800 Universal X-Stream Clamp-On Air Filter Product Reviews

Thursday, February 22, 2018 - Part RX-3800
Our 1928 Packard 526 Salon was shipped new without an air filter. The Packard's new home is on a ranch in Texas with a long driveway of caliche (dirt). The car is still driven for special events and car shows, so it had to have an air cleaner. The installation is NOT STOCK, but when you never had an air cleaner, you do what is necessary. K&N Air Filters was recommended by a vey good friend in Tucson, Jerry Schell, who owns and operates a specialty garage. I am very pleased with my experience with K & N and would recommend their products without hesitation.
