what spark plugs brand does everybody high recommed???

 

do a search man....tons of threads on this...first off we need to know your mods....

 

STOCK to MILDLY modified - stick with STOCK, factory NGK platinum/iridium 'laser' or, similar.

TURBO, NOS, S/C'd, one - two heat ranges below stock.

Don't waste your money on pulseplugs, or Bosch, or rapidfire machine gun laser etched plutonium-coated jetplugs.

 

NGK is the best in my opinion.

 

IM new to the z everybody around me have honda mostly so did i and i just got the track model 2003 just want to get people opinion?? it all stock!!!

 

i heard the new Pulstar Spark Plugs will increase more hp by as much as 10 - 17 hp... not sure if its true or not but i saw it in a few magazines and other sites

 

I would stick with OEM NGK Platinum plugs.

 

Iridiums? Allegedly, they provide a purer spark, improving MPG, hp, and reducing carbon
build-up in the combustion chamber. Can an engineer and/or mechanic in these threads
corroborate this info'?

 

NGK copper plugs

 

NGK Iridiums on a normally aspirated car, should last for 75-100K miles. Probably the last set you will buy. We carry them in stock if you need a set.

 

deffinitly NGK-R's the stock plug I believe...dont get pulstar -they are horrible quality I had them and they lasted only 10,000 miles before they started to make my car misfire, and burn themselves

 

oh and I didnt see any hp or tq increases at all with the pulstar's

 

ngk wins it
