I just got my car back from the dealer this afternoon and they took a look at my plugs (bosch platiniums) and they say that pro's don't like them. Supposedly NKG's are the best and are cheaper! I'd heard that pro's like the cheap plugs but had not yet heard it confirmed by a dealer before.

 

The Bosch Platinums seem to like lots of Voltage, as they worked fine on my GMs with HEI. But I got high rpm misfire with them in the Protege. After my second set of NGK coppers (dealer-installed at 30k service...for about $10 ea), I went with NGK Racing Platinums. I'm on my second set. I clean and check the gap every year or two with no problems. But, unless you spend a lot of time above 6k rpms, the NGK copper work just fine.

YMMV, IMHO, etc.

 

Also I noticed that the insulators of the bosch platiums were starting to peel a little, do you think they were too hot of a temperature range?

 

Oh another thing, the little nipples on aftermarket plugs ( u know the screw on ones?) they ALLWAYS keep undoing themselves no matter what I do so thank god the NKG's have an integral nipple. Has anyone else noticed the "loose nipples"?

 

where do i get nkg's?

 

i believe ur local autozone or pep boys would have them. wack pep boys, they searched my car for the spark plug list. i saw the NGK ones on the list. i was like "do u carry ngks?" they were like "no im sorry" same freakin guy that has said no to a lotta my freakin questions like K&N filter.. i hate that mo fo

 

all right..thanks

i'll stay away from pep boys

later

 

lol. pray the pepboys at ur place has better employees. that old man sucks.

 

i just got a set of bosch platinium 4+ last week. could'nt you guys told it before!

 

when purchasing the NGK vspec coppers, do they already come gapped for our cars or would we have to regap it ourselves?

 

better check it out to make sure.
