As most Subaru enthusiasts know about the ring land issues , especially on cylinder 4 with 1 of the causes being due to stagnant coolant around that cylinder. This mod helps with that. It ties into your existing heater hoses down the back of the driver’s side head and helps coolant move through that area much better. In turn helping cylinder 4 run at a more normal temperature. I sell with 45 degree and 90 degree fittings for the EJ20 Turbo engines and EJ25 Turbo engine so please make sure you know the one you need.

You will receive the following:

5/8 Silicone heater hose

4 clamps (2 installed)

45-degree fitting

5/8 “T” fitting

Cylinder head to 10an fitting

Dorman gasket

Sticker

****THIS IS FOR THE MOD WITH THE 45 DEGREE FITTING****

** DISCLAIMER **

This is not a Subaru OEM part. It is a aftermarket part.
