The dealership quoted me $250, anybody know where I can do this cheaper? My cars been getting horrible gas mileage and I believe it's because of the spark plugs.

 

what are you getting, it might be normal. i am getting under 500km a tank

 

Guelph quoted me well above the $250 for a tune up.
I read somewhere on one of these forms about some new spark plugs that give a real boost of hp. A new type, being tested. Hmmmmm where was it. I'll try to remember.

 

^I saw that thread too. Apparently no one had experienced fuel economy improvements. Butt dynos claimed more power. OTOH, the plugs don't have proven durability. Some have replaced after 6K miles.

 

I haven't changed my spark plug once yet and I have 100,000KMs now. I get about 450KM per full tank.

 

do it yourself... its easy

I just talked to a guy with a sweet Z, he told me about these Pullstar plugs he put in that are supposed to add 10hp and 7lb ft of torque to the wheels, I don't know how true that is but I'm trying to find a website for these. They are $35. a plug so a bit pricey

 

Somebody should write up a DIY.

 

search youtube for g35 spark plugs... you'll find what you need..

 

I bought that Turtle Wax ICE clear liquid polish just to try it out, its ok on the paint but works AMAZING on wheels if you have a ploished lip it will get rid of all the swirl marks and make them shine like chrome plus because its clear liquid you can get in the tightest areas and not worry about the haze if you missed a spot

 

OH CRAP I was supposed to start a nwe thread.

 

there's a couple floating around on this site... that's why we have the SEARCH function..

I've just watched all 3 of the YouTube vids and they are as good a tutorial as you can find........
Excellent help......and you can quite see why changing out plugs isn't cheap.
