Spark Plug Gs300

[martialartsguy]

can you use a irdium spark plug on a gs 300? the stock ones are platium but what if i go with a denzo irdium plug? will this mess up my engine? or just make it betrter

you won't notice a difference except the change interval-60,000 for platinum and 100,000 for the iridium cost effective the platinum works out better and is the proper plug for the car. :D :D :D

this post indicates that the platinum plugs are the proper plug for the gs3. mine is a '98. i had planned to use the ngk iridium. they seem to be hard to find. does anyone have a part number?

should i go iridium ngk or platinum?

I like the iridiums better, they will last longer! Also they are harder so less wear, better conductivity! Which means set'em and forget'em. The iridiums are only about $2 more so they are a much better deal. They may be the last plugs you buy. Here ya go.

i went ahead and ordered the standard irdium ngk's

the chart you attached above is for a '93. i have a '98. are those plugs what you recommend for the '98?

Yes, the IFR6T-11 should work just fine, or the BKR5EIX B) Make sure you compare them to your old ones and let us know how they work out.
