I know quite a few people were having problems with their stock strut bar hitting their V4 kinetix plenum including myself and it was causing some nasty vibrations in the **** pit. I solved the problem today, my strut bar was rubbing in the middle and on the drivers side edges of the plenum. I fixed this by adding 1 washer each to the front bolts on the passenger side strut bar mount and 2 washers each to the front bolts on the drivers side mounting points of the strut bar. This rotated the bar up and away from the points it was touching and solved the problem.

 

I just ordered the V4 plenum from Kinetix and I didn't know that this was an issue.
When I install it this weekend, I will take this into consideration.
Thanks for the info!!!

 

or you can easily adjust the strut bar without all this hastle. It's only turning a couple of those bolts in the middle as I did.

 

tried that, didnt work, my bar was digging into the front of the bar.
