no do it yourself the cars ecu will adapt to the change

+1. Just install it and drive.

I don't know how familiar you are working on cars, but the plenum spacer is fairly easy to do. It is nothing like headers. I installed mine (I have a Crawford plenum, not a spacer) in about an hour. The hardest part was removing the clamps behind the throttle body. Get a set of long angled needle nosed pliers.

You don't need to reset your ECU after putting on the spacer. The ECU will learn from its current level.

you need an in-lb torque wrench. follow the instructions and you'll be alright. do not overtorque the bolts.

+1^
it doesnt take to long to install the spacer youll be fine

a few have broken bolts and other mishaps by overtightening
