okay well i went to my friends shop to get my spark plugs changed, he used ngk laser iridum plugs, but when i was looking at the lancershop website, they only have the laser iridum plugs for evo 9.

so i am thinking hmmm, did he put evo 9 spark plugs in my car? i think i read that evo 9 plugs are too long so it would not fit anyways but i just want to clarify that?

please someone let me know asap.

 

The Evo 9 plugs threads are longer than the Evo 8's.

 

Bpr7es - Evo Viii
Ilfr7h - Evo Ix

 

alright so their would be no way that the distributors would have connected?

 

Wrong end, the threaded end is longer. I would think a longer threaded IX plug, would hit the piston on a VIII.

 

Actually the electrode would stick further into the cylinder which may(not 100% sure) cause the piston to hit them. The coils would go on fine. Like I said, the threads are longer.

 

oh my goodness? okay so if the pistons were hitting the plugs would this cause some significant dmg? i have had the plugs on my car for about 600 miles now but nothing seems bad?

 

If they were hitting, your car wouldn't be running right now. You should be fine.

 

okay so i should be okay then? also do they make the laser iridium ngk plugs for the evo 8 then?

 

This would have been a better question to ask if you actually KNEW what plugs got installed, IE see part #

 

well does any one know anything else? i have driven over 600 miles since i change the plugs, and the car runs fine? if they were evo 9 and they didnt hit the pistons then would my car being running fine or not?

do they make ngk laser iridiums for 2003 evos?

 

argh now i talked to my friend with the shop and he said that the distributors say that the plugs are for evo 8 and 9 what the heck? please someone tell me something for sure.

should my car be running like crap if the plugs are bad, or what/\?

 

Dude, no one can help you without a part #. Get the brand and part number of the plug or stop posting. WE CANNOT GUESS OUT OF THE THOUSANDS OF PLUGS IN THE WORLD WHAT IS INSTALLED.
