Throttle body Spacer on 5.3 chevy V8????

[H20 Party Starter]

Anyone install one of these throttle body spacers on any late model Gas v8's?
I'm curious if they work well, or if you can even notice a difference.
I've always run K&N intake/filters and flomaster exhaust on my trucks and am looking for stuff to order on my new 06 silverado (Thanks Jay :cool: )
Any input?????
Thanks crew

Might have a problem with the intake kit as the spacer forces everything forward toward the radiator on GM trucks and that plays havoc with bracket alignment. Not saying it can't be done but kit installation will not be straight forward and will require some fabrication. Our testing shows them (spacers) to be most effective at higher RPMs out of what we consider "normal" driving ranges. The intake kit, however, begins increasing performance at a much lower RPM and is therefore more useful to everyday driving.

You'll have an overall rise in Vollumetric effeciency but your best bet is to run a high flow exhaust and cat, at least 450cid, headers and a high flow intake. Design of the engine depends on the Thermal effeciency of the engine with the mods. Remember you'll get better gas mileage with all the mods as long as you don't put your foot on it too much but if you realy want better gas mileage and power, Turbo charge it - Fk nomaly aspirated engines.

Thanks for the input, I guess I'll hold off on the spacer and see how the intake and exhaust does. This motor is the new generation 5.3 All alum. block, supposed to be 15 more horsepower stock than the other 5.3's. It's only got 400 miles on it, so I'm waiting for a little more break-in time before I see what she can really do :)
I do already know for sure that the rear end deffinately has a locker ;) :D

Pro Charger makes a nice kit for the new 5.3 :rollside:
