Spark Plug Recommendations

I am looking to change the plugs again. I went with the NGK Ir's before, and there was nothing really special about them for the price. I want to do something that is a lot cheapier, but will still give a really strong spark. It doesn't have to last more than 30k either. Any opinions on what you use or have heard would help. The plug needs to be available also. I don't want to have to wait a week.

 

go with CHEAP NGK copper plugs. You just need to change little more often. (mostly every 7k-10k miles)

 

SS says they can help advance timing... not sure how that works though

 

Cool, that is what I was thinking also. I am not concerned about longevity, which is why the Pt's and Ir's were made. I actually enjoy changing the plugs and enjoy the responsiveness of new plugs.

 

NGK bkr7es also known as 3330's thats what we made 407hp with on a stock EJ205. Gap them down to 28 and let it ride.

are those one step colder ?

Correct, one step colder than stock.

For you guys in the 200-250 range you can probally gap them out to about 30 but if you are making more than 250 then I would go ahead and gap them down to 28.

 

what exaclty does it mean by colder?

after regapping
does the computer take over timing adjustments
(i had to retime on my nissans)

 

You shouldnt have to make any timing changes when you regap plugs.
