I installed primitive racing plates on my 2021 Subaru Ascendant about 6 months ago. Since then there is a strange vibration when taking tight turns and when accelerating from a stop. I have checked the installation several times and everything seems solid as a rock. The vibration seems to be coming from the turbo cooling duct, is it possible that the cooling duct is rubbing something? I tried to find something, but I didn’t see any problem.
One question I had is the cooling duct attached to the skid plate is supposed to slide under the cooling duct attached to the front of the car, or over it? (Please see attached photos).
Turbo channel of the skid plate goes down.
The Turbo Channel skid plate goes on top.
I tried both ways of installing the turbo duct, but I still have vibration. Do you have any suggestions?
Thank you!
