Confused about spark plugs...see Mazdacomps list
Mazdacomp is currently running a sale on ther competition parts...10% off!
I figure that I would buy some perishables like the 99 spec front brake pads, etc...
I was going to purchase the some spark plugs but noticed the variety of spark plug and comments next to them....
which one is recommend in a car running 99 turbos at 1bar, streetport and HKS twinpower? I'm alittle confused after doing a search in the 3rd gen section

Mazdacomp told me the EGV plugs is an old NGK racing plug model (which is why they are cheaper) but they recommended NOT using them with stock turbos. I wish I could remember why.

For a pretty stock car with little modifications you want to run BUR7QEP and BUR9QEP. P stands for Platinum. If you want to a cheaper plugs but still want NGK's, just get the BUR7QE and BUR9QE....this is from memory. I don't know for sure. If you have access to Mazdacomp, you can access their PDF parts catalog and it will show you more.

There is a scale to figure out how much colder you need to go but I can't remember it or the link but 1 bar would be 8's/10's (as I am running). My mechanic told me to run all 10's but I don't see the purpose of running just as cold leading when it fires 1/2 as often. I think it was 1 # colder for every 4-6lbs of boost. If some one has the link or can correct me (nicely), please post a response. btw, without a membership you can not purchase from Mazdacomp.

hey bob,
you can run either 9s all around or race plugs (10s, 10.5s, 11s etc) leading and 9s trailing.
You dont want the race plugs in just trailing, they don't do much of the combustion work at all.
Call steve at gotham or chris and ari up and they can help you, both places stock all the plugs i mentioned.

That is:
R6725-105 is 10.5
R6725-11 is 11
R6725-115 is 11.5
and the T813JN-13 is a surface discharge nickel alloy plug.

Denso Racing Iridium IRE01-27....wow these are awesome plugs...TINY electrode (0.4 mm), no doubt would clean up the top end on many of these cars and eliminate the need for that silly "Twin Power" gadget
the std NGK rotary plugs are crap, and non-gappable...don't go cheap on plugs, and don't use a super cold plug just because of paranoia over detonation

aside from carbon build up I dont see why you say the Denso Iridiums did not perform well....the real issue here is electrode wear, the solution to carbon build up is either a hotter plug or a lead foot
