2002-2007 Subaru WRX / STi Aluminum Racing Radiator : Megan Racing MR-RT-SI04ST

Model Number : MR-RT-SI04ST

We are proud to introduce the new Megan Racing high performance aluminum radiator. Anytime an individual introduces their car to a racing/drifting environment, the temperature of the vehicles engine will skyrocket. One common and effective method of reducing engine temperature is to employ an aluminum radiator. 

This is a cost effective upgrade which can ultimately save an engine during competition or spirited driving. Often times, a temperature drop of twenty degrees or more will be noticed when using an aluminum radiator. Also included is a 1.1 BAR radiator cap.

ATTN: Please FLUSH the radiator before installation and properly take all the air pockets out. If its not properly installed, might cause the motor to over heat due to low coolant or air pockets in the cooling system.

- 2 rows
- 02-07 WRX/STi only
- Radiator drain plug thread size is 1/4-18NPT

NOTE: 2002-2003 Subaru Impreza WRX's only have 1 "radiator cap" on the coolant reservoir on the intake manifold. For later models, Subaru added a second radiator cap since it is difficult to completely fill the system through the one cap. 2004+ vehicles have two radiator caps-- one on the radiator and one on the reservoir. Please be sure to purchase the correct radiator for your application. 

- CAN FIT 02-03 MODEL WRX, just leave the cap closed.

- Due to extra radiator thickness and limited clearances behind the radiator, the upper radiator hose may need to be modified to fit the radiator-- more specifically it will need to be trimmed/cut slightly shorter to accommodate larger radiator. Take careful clearance measurements prior to making final cut-- measure twice, cut once!
