Don\'t know if anyone can help me on this,
I\'ve got a Mazdaspeed AST for my car, but the supplied cap is rated at 1.3Bar which is way too high!
The factory cap will fit but it\'s a very tight fit which makes me think the cap will not work properly.
Does anyone know where I might be able to get hold of a 0.9 Bar replacement?
I\'ve noticed Re-Amemiya supply their AST with a 0.9 Bar cap but can\'t seem to find it on it\'s own, only with the kit.
