Whats a good Remote Oil Filter Kit for 340/360?

Fratz; it doesn't add oil but helps what is there flow smoother and quicker since it is not restricted to a smaller passage that has multiple 90* turns. I don't think it will be a whole lot cooler. But adding a oil cooler at this stage is also easy and IMO a worthwhile thing to do.

Adding life to oil is a matter of keeping it cool, away from the rotating assembly, and not beatin the crap out of your engine because oil is whT protects the engine. Beating on the engine is also beating up on your oil.

Sedan; you are correct! 1/2 hose and not heater hose. Call Summit and ask them for some hose. Or your local auto parts store, not rod shop etc....
Figure that the engine oil will see high temps and pressures.
The hose surplied in the Summit kit has "Goodyear" stamped on it.

The only thing in the kit I would change out is the straight fittings on the block adapter. A change to a 90* or 45* soft bend is what I would like to do later. The straight fitting has the hose bending away from the frame. It is not kinking, but it is laying on the subframe. I'll need something to hold the oil hose away from the body and frame.

I also want to mount the oil filter where the charcoal canister is. I'll need another 8 feet of hose. The kit came with 8 feet.

This mod is easy and it makes oil filter changes a snap plus a whole lot cleaner. No oil on the headers, ground as well as a whole lot less on your hands, arm, hair, eyes, etc.... LOL!
