How easy is it to change the plugs in an 02 Z? what brand would you suggest? Thanks.

 

NGK. I am not sure the level of difficulty on the LS1, but have seen a few threads around here asking how to change the passenger side (I am assuming it is the harder side). You ought to be able to look at your engine to see how hard it would be though.

 

lol the drivers side is a sinch! the passenger side is a *****, tomorrow im going to try and go from under and if i cant to that im paying someone to do it....
