im just wondering where can you get a stiffer sleeve for the part where u stick onto the throttle body? i just got a cheapie intake off of ebay and the sleeves it came with are kinda flimsy and doesnt hold the intake in as stiff so it kinda bends and flops.. jus wondering where can you get the stiffer sleeves like the ones injen,aem, etc, comes with..

 

are you speaking of couplers?...when you say sleeves?...uh you can go back on ebay and buy aem couplers..
