Are there any known good spark plugs for a s tock AP1?

 

Stock plugs

 

NGK V Power

I use them on my Boosted S2k

NGK R5672A-8

 

i use denso ik22

 

Otherwise known as NGK 7173.

Those plugs will work great for a stock car and even a boosted car. I've never had a fowling problem with them.

They are copper though and they also are resistor-less. Some people want platinum or iridium for longevity. Some people think resistor-less plugs can ruin things.

If you want a plug that'll last longer than you probably will own the car and work with no problems, then get the oem double platinum NGK plugs.

 

it's really about the heat range the plugs offer for your application. ask around and find out what you are going to do. for light NA mods, stock plugs will do the job. if you are going all out, you may want to look into getting platinum or iridium plugs with a different heat range.

 

I read in Hiper Rev Vol.2 that if you are going to rev the engine at all you should have atleast a #8 plug and if you are going to track the car you should have a #9 plug.

Any thoughts on this?

 

Really? That's pretty wild ...

What mods do you have done to the car, and/or plan on doing in the near future?

Platinum plugs last forever, but they can't be re-gapped, so if you're going to use boost any time soon, copper is a better way to go; however, if you just want a reliable plug to use on a stock or near-stock car, platinum will last longer.

The stock NGKs are great plugs though, I've never had a problem with them fouling (although only around 40k miles on the car). Are you having problems with your stock plugs?

karts should be different b/c you're running a carb and no ECU, right?
