Top Quality
Great quality mod for any STI. Shipping was quick and as always, the customer services is top notch. Thanks!
Great Product and Great Service.
I got the plastic T version and am very happy with it. Install was simple but it took quite a little wiggling and twisting the get the factory 5/8 heater core line onto the plastic T I would recommend using a little lube to make it easier. Other than that the kit is great quality! Thank you Nick for your help and you are right the plastic T is perfectly fine and I do not anticipate any issues down the road.
Number 1 mod for ej motors
Best mod for the ej engines Keeps you coolant temperature lower for longer and prevents cylinder 4 from knocking what else do you want? This is a no brainier mod.
100% Needed
After reading tons of info and hearing first hand experiences with the benefits of this item its clear that this is needed in order to better protect the 4th cylinder. While there is no performance gain from this it helps the longevity of your EJ motor. Tricky to install but worth it.
