Hey Alan, Give me a call after reading the message below if you have anymore questions! -Michael (507) 215-3817 Yes the wave modification will be placed in the intake tube closest to the manifold connection. The crankcase breather tube going into that connection piece needs to be removed, cut back a few inches to be sure the wave air does not get interrupted. Simple to do for you at home with a wrench and a sawzall. Just reinstall and it’s ready to go. The only downtime needed for your truck is when you swap out the intake pieces. I’ll provide the replacement and locate the piece once the order has been placed. You’ll also get a 10ML engine restoration treatment at no charge! Average turnaround time is 9-12 days.
