I just ordered the SLP lid and I want to get the smooth bellows to go along with it. Does anybody know if there is a performance difference in the $50 bellows from SLP and the $20 ones being sold on ebay?
I guess I have the $20 one, but I bought it from a truck-parts company for like $11. Its hard rubber and I've heard it breaks the 'tabs' on the back of the lid when the engine 'moves'(torque). Mine is still in the box.
They say guys running 10/11 sec 1/4 mile....are running with the stock 'flex-hose'
I'd save my $$$$$$

Ive seen the tabs on lids crack when folks have swapped out the hose and maf ends.
As Tom said, you need some give because the motor flexes. The lid assembly is fixed to the radiator support. When the motor moves, if there's no give, something will eventually crack and/or break. Thats why the stock hose is a "flex" hose.

Have the bellows on and am thinking of taking it off just for the fact is I got the performance lid painter and it does make it a little stiffer. Have a mark on the lid because I didnt have it pushed down enough, So I now have a small mark on the lid Posts: 3091 | From: Canton Mi. | Registered: Oct 2002

I opted for the SLP smooth bellows, a few years ago, for the reasons ChrisL stated. I remember a post by JeffY on the SLP board about material used in the bellows, and the benefits of the bellows being able to flex to compensate for engine vibration and torque. Having the bellows able to flex seems logical. I typically go the safe route with any mod, and the SLP bellows seems the safe way to go with this mod.

It is pricey. I guess, looking back, I went for the smooth bellows for the same reason I bought a pair of FRC's - appearance. Both the bellows and and FRC's look good and I think add to the appearance of the engine compartment. I seldom drive my SS to the extreme, and probably have not realized the max performance gain changing out the bellows. Going the safe (and expensive) route with SLP prevented possible damage to the even more expensive air box. Posts: 2359 | From: Waterloo, Ontario, Canada | Registered: Jul 2001

Makes a 1hp difference at best. Mine pulled my lid of several times so I sold it. Put the money towards a suspension goody where you can see a gain. My .02
