I got a set of NGK 6097 but I've heard from the performance shop that NGK copper V-power don't last long you have to change them so often compare to Denso that last longer even just regular line, they are almost as cheap as NGK. It has something to do with the electrode design, I want to try them to see the differenceGary":2x0osdao said:PK20R8 = BKR6E
20 is the heat range, higher is colder for Denso.
Question: Isn't the NGK is easier to find?

Copper is still copper, it won't last long like iridium or platinum.
Many of us change them out when they change the oil.
It's a good check up too.
try it and let us know.

Do you happen to have a dyno of your honda? I'm interested to see the torque figures and power curve.
Thanks
Well, it will take 2 years for my car to reach 10k miles.SLC Punk":3t2nj2yh said:Gary":3t2nj2yh said:I see your point.

:shock: You guys really change your spark plugs out every 3-5K miles!?!?
I have gone 10k on my spark plugs, maybe its time for a new set! :shrug:

Normally, I change plugs twice a year (around 2500 miles) and oil 3-4 times a year, not because of the mileage, but because of the temperature/season.

As for changing the oil- I'm at like 3000 miles and I have 4 oil changes under my belt I beat the car hard and I regard fresh oil as cheap insirance. I literally check my oil every day that I run my car.
