Well...yeah...telling me my Safely Modding thread is useless? Your good in my book. I tell you to buy headers up front if you have the coin. If not...then buy a PLOG, DP INSTEAD.
Coils...are eye candy...you just wasted $200. Bosch plugs suck more wang than a 3.4" with no other mods.
So...good job wasting that "serious cash"...
I was expecting something in the neighborhood of 5 grand...not $400.
