Guys i have 38K on my max take very good car of my car when should i change the plugs and what brand is good

 

Oh at about 80-100K miles...

 

If you do lots of highway driving, I suspect they will go to 100K. Because I was pulling my intake off to install the Phenolic spacers, I decided to replaced the plugs with the NGK Iridium. You have to remove part of the intake to have enough space to lift the ignition coils near the firewall(yes, one coil over each spark plug) and then pull the plugs. Do you fell lucky!

NGK Iridium are compatible with NOX.

 

I was thinkin of replacing mine whenever I buy the IM spacer kit, I think im about at 60k, prolly be around 65 by then. I need to find a spare IM first.

 

Interesting

 

Why a spare IM?

 

Read the Owners' Manual. But the 100 K mile estimate is close.

I recommend you track your gas mileage. When it starts to fall off at aroung 100 K miles, you know its time to replace them.

If you drive a lot of highway miles, I suspect you could get up to about 120 K miles.

 

Cause I needs to take advantage of the top end powaz!

 

From the FSM:
Spark plugs (PLATINUMTIPPED type) Replace every 105,000 miles (169,000 km).

 

i am getting close to 114k miles and I have to get mine replaced soon. I'm trying to find a place that won't rape my wallet. Most mechanics are quoting me for atleast 4 hours of work....
I'll take care of my inspection next month and then take care of the maintenance..

 

No use messing with a good thing. If you are not having problems with your car don't change them untill the recommended mileage.
