when putting in some 42 lb injectors, i noticed my injectors in my 06 cobalt were a tad longer than the 42's i had from a stage 2 ss/sc. and had a bit of a wiggle, therefore a word of advice is that u should have a ss/sc fuel rail to solve this issue on hand if it is the same for ur car. luckily i did. unless u want fuel to spray everywhere

 

what you need those for? mods planned?

I dont think i have 42's

 

 

mkculrley urs are 40's i belive, not sure i think hahn pm'd me and offered me direct replacements 40's...or they could of been 42's, i i deleted it a long time ago though

 

just some test fitting ive been doing

hahn has to be running different injectors that the 42's that come in cobalt ss stage 2's.

and everyone who HAS been doing this with them should double check their stuff right away.
