03TNSSS Posted September 11, 2008 Report Share Posted September 11, 2008 Ok guys I feel really dumb for not knowing this, but what in the world is the difference between a LQ4 and a LQ9? I have a 2003 SSS. What motor is this? Are all of the SSS engines the same "LQ-" classification? Just lookin for some knowledge. Thanks.

I've been wondering that forever! Haha! Are there casting numbers that specify which is which? And where are they? Quote Link to comment Share on other sites More sharing options...
