I got the car at 29k miles, and it's now 47k, not really sure if last owner ever change spark plugs.

How would I know it's time to change it? the car is running just fine right now.

 

I would change them. Maintenance is cheap but will go along way to making your car last longer and gives you peace of mind.

 

Doesn't the dealer change them at 75k lol?

 

NGK Copper part# BKR6E-11, you can get a complete set for under $10.

Copper plugs you should change every 15-20k miles. Platinum I would change every 40k miles, so you are due I would say.

Not too much faith in platinum....

 

I run the S2000 Platnium Plugs. They are a 7 heat range instead of a 6.
They are also the plugs which come stock in the JDM ITR motors.

The only down side is since they are platnium, they run about $17 a piece.

 

Just changed mine today with Denso Plat. Cost me $6 a plug. Cheap to do. I say go for it.

 

I just use the regular normal NGKs, the guy at the dealer told me they require the Iridium or platnum or whatever the heck and I asked to speak with someone else
