8 popular GM filters compared. All of these filters are very good and imho 2 are outstanding.

This is the filter spec is used on my stroked LT1 383 powered 1992 Corvette (which is why I was interested in doing this comparison), and, this is a super popular filter, used in millions of GM cars. Models listed below.

Update: even though I purchased all filter new, the Fram Titanium was slightly old stock, and it's construction is actually exactly like the Fram Ultra filter.

Full Disclosure: my 1992 Corvette has a pretty rare Lingenfelter built engine and it is amazing. I feel very lucky to be the owner of this car. It sees numerous track and autocross days each year, and it's 30+ years old, so choosing the very best available filter and oil for optimal performance and protection is super important to me. I was using a Mobil 1 filter (a good option) and, thanks to doing this comparison, moving forward I will be using a Bosch Premium 3430 filter paired with Mobil 1 Supercar 5w50 oil.

Every filter tested would be a good choice. The Bosch Premium's 99% at 20 micron rating, lots of pleats / filter area, large ovalized inlet holes and solid bottom plate with no bypass valve were the qualities that in combination led to me selecting it for my Lingenfelter Corvette. Oil will be changed at least annually not more than 3,000 mile OCIs.

All 8 Filters are ultimately made by 2 parent companies: First Brands (Fram, Champion Labs - AC Delco) and Mann-Hummel (Purolator, Wix, Bosch, Mobil 1).
