Not to kick a dead horse, but I accidentally ended up with a really large oil filter that crossed over from the FL400S and that is the Wix 51516/NAPA 1516... it actually helped oil temps even more than the FL400S and for those of you with still a stock radiator you can also go with the Fram 3600 (NEVER orange Extra Guard, use silver Tough Guard and gold Ultra Synthetic only. Extended guard is a waste with our OCI's on a turbo car) and that mother almost hits the stock radiator shroud... It was 100 degrees yesterday and driving 70mph and accelerating up hills I barely broke 220 for very max oil temp with the NAPA 41516 (Platinum). It's really clear these longer filters taking more oil and the heat sink effect of more surface area REALLY helps keep the temps down! Forget oil coolers, people, save your pennies for a radiator and just use a giant oil filter!
