Well packaged product and obviously easy to install. Love the blue gaskets on them and they work very well to maintain system pressures. Would definitely recommend this product to anyone building their Subaru to higher horsepower levels.

if installing on sti you need to purchase 2 but i havent seen any noticeable difference and just like stock caps they have the 1.3bar on the radiator and 1.1bar on the secondary filler area so i just staggered 1.5bar and 1.3bar

This cap began leaking coolant shortly after it was installed. I began thinking it was a head gasket issue or the overflow lines, but after much frustration, I traced the problem back to the cap. After replacing it with the stock unit, the problem immediately disappeared and the smell of burning coolant after each drive is gone. As always, customer service at RSD was quick to remedy the problem and their support is to notch. I always assumed coswortth was a byword for quality, but in this case I was disappointed
