Review on JDMSPEED Left Intake Manifold Adjusting Unit DISA Valve Replacement | BMW 135i 328i 530i 528i X5 Z4 by Pete Deutsch

Delivered quickly. I installed it on my E70. It fits well and solves my DISA valve problem right away. It appears to be of good quality and in fact identical to my original part. The car has 126,000 miles on it and drives like it did when I bought it brand new. Let's see if the new valve lasts as long as the original. Time will tell, but so far I'm happy with my purchase decision. Saves a lot of $ too!
