Well, everything passed with flying colors...hell they even passed me on my EVAP system (Which I don't have Question )

HC was half the limit...
CO was significantly lower than the limit...
Passed OBD Codes (Thank you HPTuners!!! Laughing )

Only thing was NOx output...over 4 times the limit!!! My guess is that this reading is high because the combustion temps are too high...I am running stock plugs on the L32 (Iridiums) and no EGR (I know that would fix that, but I'm determined to pass with no EVAP and no EGR!!!) I think AL104's will extract enough heat from the combustion chamber to pass the test...thoughts?

Remember, this is all on E85 with no EGR or EVAP Twisted Evil

Have no idea there, wouldn't you want a colder burning plug? I do know that last time I passed emissions with my EGR bypassed. lol I would have failed with one more hydrocarbon, no joke, 219/220. lol

Haha thats funny...

Yeah thats my idea, Iridiums burn all kinds f hot, and AL104's burn WAY cooler. Like 3-4 steps I think.

Since your running boost, I would think you would want to put similar plugs in to that of the L67?

Yeah its weird though, I am running the plugs that came with the stock L32 motor (basically a newer L67) and I guess they burn WAY too hot for emissions Confused

Update! Found a vacuum leak. Caused LTFT's and STFT's to be maxxed out causing a super duper lean condition. Car should pass with flying colors now Smile

Hate them! But it's kind of bogus because the aftermarket adapter plate for the Gen V blower to a 97 throttle body totally doesn't cover up on of the passages Confused It was just a huge hole for unmetered air to enter the motor!
