I got one of these bad Larry's for free today. Im wondering if its worth my trouble to toss this thing on. I have a PP 75MM plenum, t/b, CAI whatever. My car is N/A..... worth it?
intake spacer... useless?

At least it's more erect and not floppy anymore.
Waste of time and effort

Huh thats funny, i have a tb and plenum with both spacers and one it increased my mpg quite a bit and two throttle response picked up a lot. I'd say if you already have it put it on there.

Most (not all) aftermarket plenums are raised around an inch also, so that kind of works as a spacer in itself.

If you installed them all at the same time thats prolly why. If not, its your imagination making you think something changed so you don't feel bad you wasted money. LOL

Agreed.If the spacer is used on a ported stock upper,it's "almost" the cheap way of doing what the aftermarket upper is doing,creating more plenum volume,but you will see very little gains.If it's free,and you are running the stock upper plenum,put it on,i did the same,got one for free,and trew it on.Who cares....it's free.But if you have an aftermarket upper,i wouldn't bother,no point in it at all .

No i did the tb then an few months later i did the tb and plenum spacer,then about 2 years later i did the plenum, and each time throttle response and mpg got a little better. Trust me i'm not just saying that so i don't feel bad about wasting 50 bucks, thats not that much.
If your PP plenum sits somewhat higher than stock, then adding the spacer might cause your hood blanket to touch / rub the plenum.
