When to change spark plugs?

NO2MORO · 05-12-2005, 09:56 PM

When should I change out the NGK plugs in my car. I now have 28,000 miles on the car. When I drive the car I drive it hard. I noticed the other day that when I am just cruzing along at one speed It has a miss feel to it. The RPM gauge does not drop, but it feels like you just tapped the brakes.

I would pull them and see what they look like. Tim recommended going with the TR7's while I had the TR6's in when he tuned it so I bought a set from him. I checked them the other day and they looked just like they did when I put them in, so i'm leaving them alone for the time being. What gap are you running?

I'd say that's more than likely your tune. Mine does that too.

You probably haven't noticed it until now cause you trailer the car most everywhere it goes.

Hey man,
What's your car look like? I live in Leeds in Oliver Crossings. I'm sure I'll see or have seen you around.

edit: NM, Josh. I guess its black.

Travis, I've had the same plugs in my car for over a year. I am getting ready to change them out. I'll prolly go with the same Autolite 764's.

I was going to offer you so help when you move but now I will have to think about it a little longer. That trailer will hold alot of furniture.

I have not seen him around the area either, but we did meet him at Steele last year at a thursday night test and tune.

I change mine out every year whether they need it or not.

That because you keep modding your car and changing heads. We can't really change heads, well we can, but they all use the same style of plug.
