If you are tired of your OEM plastic radiator cracking or just simply looking for an upgrade, the 4thgen radiator is a very good option. It fits perfectly on the 2000-2003 5thgen and only costs around $100 bucks. The quality is great and equal to those of other known brands like Mishimoto and Megan (in my opinion). I have been running this radiator on my Supercharged 5thgen with no issues for years now. This post contains all the details you need to know.

Important Note for Automatic Transmission Owners

You will notice that most aluminum radiators say “Manual Transmission Only”. This is because the Automatics have a cooling hose that flows between the radiator to the transmission. You can easily purchase a transmission external oil cooler and you will be all set. One of the most commonly used brands is Hayden and you can find it any local parts store. Below are some reference photos. Here’s a link to a write-up which can be helpful:
