:...I see no recommendations on stillen's website and the oil cooler kit for the na does not come with the restrictors in the oil lines which means it has to be hooked up inline with the oil flow to the motor which means that it will be getting full engine pressure.........make sure you know that what you are saying is true..and some sites to back it up would be nice too :)
However, there is no oil cooler application listed on Stillen's site for an NA. The one listed is for a TT. The use of restrictors does not determine whether the oil cooler sees full engine pressure. The stock TT uses a bypass valve to bleed off excess oil pressure to the oil cooler. The only way you'll get full pressure to the cooler is by blocking off the bypass valve and using a sandwich adaptor, which is not listed on Stillen's site.
