is it worth it to install a 3/8" intake spacer while i have the manifold off to put my afpr on? will it improve horsepower and torque like a carb spacer or is it useless.
thx in advance

I added the spacer...I thought it added some low end tq...but then again that was based on sotp. Cant hurt to do it.

By increasing the runner length you will increase low end power but suffer on the high end. If you have an auto go for it. I have a heat spacer on my standard trans car but that is only for valve cover clearance.

It is used primarily to create valve cover clearance. The extra runner length may affect power/torque curves - a bit more torque at lower rpm; a bit less power at peak -- but nothing significant. If you're iceing intake components at the strip between rounds, it may let you cool the upper down a bit more effectively. But as a practical matter - if you need more clearance, use the spacer. If you're looking for more performance, spend your money elsewhere.

go ahead and get it! Im not sure if it adds any noticeable HP, but i can definetly tell the upper intake is not nearly as hot as it was before!!

Spacer or no, on a street car, the upper is gonna heat sink to the same temp it always has.....it might take a bit longer with the spacer, but it's still gonna get just as warm.

I wouldn't use a 1". I used one on a previous combonation and it KILLED the top end power of my edelbrock performer intake. It was on for about an hour and off it came and on went a 3/8". Just enough to clear everything I needed too, and BTW the 3/8 IMO didn't add any gains that you could honestly say could be felt. I agree with Michael Yount, unless it's for clearance, I'd spend money elsewhere.

I suppose I should add, I use a 1" on mine for clearance between the valve cover and the throttle body linkage. I have no egr spacer, and when I moved the throttle body that much closer to the intake, the bottom of it hit my Cobra valve covers. The spacer resolved that - and based on some temp. data I took when building my cold air box and relocating my ACT sensor, I don't think it made any difference on intake air temps - other than perhaps keeping them a bit lower for a bit longer - til the upper heat sinks along with everything else in the compartment.

i have gobs of top end to spare with my set up.....and if a 1 inch spacer gives me some low end thats fine
thanks for the insight i think im gonna go with a 3/8" spacer. its only $20 i dont got much to lose
