The only one that had a listing was Fram. It had a listing for cars and trucks. My engine is of the 58-62 vintage and is reportedly out of an El Camino, so I'm assuming I should use the car filter, right? Is there actually any difference between the two? Is one a higher capacity than the other? | | | | | Joined: Sep 2006 Posts: 2,393 Shop Shark | | Shop Shark Joined: Sep 2006 Posts: 2,393 | There would be no difference. By the way I recently found that FRAM is recalling certain High Performance filters, so stay away from any # preceded by the letters HP.

The dealer installed ones were AC. The aftermarket was made by Fram. The quickest way to tell the difference is the AC uses a 5/8 wrench on the cover bolt & Fram uses a 7/8 & sometimes has a big wing nut. You must get the right cartridge even though they make replacements for the other brand.
They say money can't buy happiness. It can buy old Chevy trucks though.

Fram# C4P
Wix# 51100
Wix filters are generally better quality and available at NAPA.
216 bypass canisters were smaller and early 261 bypass were larger than the 235.
Larger size filters need replacement less often. | | | | | Joined: Aug 2005 Posts: 341 'Bolter | | 'Bolter Joined: Aug 2005 Posts: 341 | If you can't find the WIX at NAPA I can get one through AMSOIL for you.
