why are you putting colder plugs in a N/A engine? that makes no sense at all. especially stock. im with him.
make a FWI, put stock plugs in with the stock gap, 180tstat, 2.5 DP from zzp cat or catless (just go catless) go with ported front manifold, maybe even go ahead and upgrade the wires, if you do cam i say go with the GT cam from ZZP my buddy had one and it was really nice and provied alot of power for his regal. i have the HV3 and it makes a huge diff, you really feel it. i say do this. in order.
1. change plugs.
2. FWI
3. 180tstat
4. 2.5DP
5. Ported manifold
6. HV3.
7. Rockers (easier to install)
8. check your tranny now.
9. upgrade suspension.
lol. thats just my 0.2 cents.
