Do some research, it is a Fram rebrand if memory serves according to a bunch of online tests. If it is not a Fram rebrand, it is a Fram clone with similer Fram internals. For my engine it is K&N or Purilator ONLY. When you see a failed Fram or Fram clone on your engine, it is scary shit indeed...especially when you take the time and money to build that motor yourself by hand. I am sure I nearly lost a Ford motor or two to the Fram crappiness.

Regardless of if Matt's research and my tired ass research agree, we both agree on K&N as being a good solid filter.

Like the Champ filter, this filter is made by Champion Labs. However, it uses a unique end plate and a thicker can that make it the strongest filter available for wide distribution retail sale. It also uses a synthetic media, which inproves filtration and flow. I'm happy to say that this filter is NOT a fake. It is definitely a unique design.
It uses a synthetic fiber element that can filter out very small particles and is very strong. It is rated just under the Purolator Pure One as far as filtering capability, but is still very much above conventional paper filters. It also has a very strong construction to withstand high pressure spikes during start-up. However, as with all Mobil 1 products, expect to pay 2 - 3 times as much for this filter.

I have received many reports of these filters failing at high pressures. It seems that the seam where the backplate crimps to the case can split.

I would use Mobil 1 mineral oil in 10w 30 if I could find it for my SR, but wind up using Valvoiline of the same specs in mineral oil. Didn't know if that information I conveyed was clear.
