Why cut the thermostat?

[GlennSullivan]

Ive run K&N on all of my high performance cars for the last 20 years and the secret is to not oil them at all. Use them as you would any ordinary paper filter - one that flows 1.5 times as much air as paper, and throw them away when they are dirty. Don’t believe the BS about the “forever filter”.

When you say "transaxle shift motor" do you mean the transfer case shift motor?

This is the mentality that brought me lots of engines! If you only drive around in town it's probably fine, but throw in some sand/silica dust and it'll tear up valve seats and cylinder walls. If it's got a turbo it'll eat the blades down just like a boat prop that's seen too many beaches.

Not to hijack the thread, but any filter that flows more is letting larger stuff through.
It's physics.
Air filters and cold air intakes have great marketing teams.
