is there much aftermarket support for the LZ4? I bought an 07 impala the other day to replace my cavalier z24. I'm wondering what I can do to give it some more passing power, I've done some looking but haven't found much.

Thats kinda what I figured. It seems that the K&N for the 5.3L impalas will fit, and i'll probably tune it and be done then.Originally posted by SappySE107 View PostPretty much no. Short life span, and not nearly enough in common with the older engines to work with.91' Cavalier z24 A3: cai, muffler (no fart can)
