Cusco 1.3 Bar Radiator Cap Type A

These caps clean your bay up, give it that little spice, and it lets people know that you love name brand! Don’t cheap out get a few of these baddies!

I am seriously NOT a mechanic or subaru specialist in any way. I have been driving STI's and WRX's since 2000's, but never really considered these little parts that contributes to making a difference in the long run. I always believed big parts such as aftermarket turbo or bigger parts made a difference back then. But since getting the 22 wrx (and not totally satisfied with it at first with all stock parts), I started researching more on small parts that makes a difference (to keep my warranty). Now mind you this part is in combination with carbon filter removal and Grimmspeed dry con air filter. Stock exhaust except ETS axleback exhaust for further clarification. Not just the radiator cap alone.

Yes...this increased pressure from factory to 1.3 bar DOES make a difference. The idle rev is a bit more powerful, and the PSI on the turbo did increase a bit after installing this. I am a true stickler when it comes to observing performance on stock parts vs. aftermarket parts.

It's a worthy investment.

Again, thank you SubieMods.

2019 Crosstrek straight forward install and looks great

Some may argue, but there was a notable difference. I wont be setting and speed records, but it feels like the steering wheel stiffened up. Very happy with the product. Looks great too.

Had a mishimoto reservoir tank on my 02 WRX, the mishimoto cap started leaking so I bought this one and it fits! Hope this helps
