It fits. But not as well as standard hose.
I bought it as my original hose had gone soft. This one came and I was impressed. Felt hard and matched the shape perfectly. Problems I’ve had it doesn’t have the grooves to fit properly like oem. And I think because of this I’ve had to pull up roadside 3x in the first week to fit it back on as it’s blown off. Yes I had tightened the clip up. Since I’ve changed the clip to a better one and been able to get more pressure keeping it on.
Did it gain any performance..? I don’t think so. Defo nothing notable
