so my G finally went into get it new plugs put in @ 107k miles (NGK laser platinums) dont really care about the laser name or w/e it was the only ones in stock. Also going to take care of a rattle underneath im hoping is just the shield. Though I haven't noticed any loss in performance and barely any on the fuel economy end (owned since 45k), will I notice a difference with the new plugs? and also my car is no longer a daily driver as my 97 accord takes that roll.. what do u recommend to keep the G fresh..

 

most likely you will not notice a thing. you might get a placebo effect thinking it runs smoother and revs faster or .1 MPG better. But in most aspect you should not see a difference unless something was wrong. Its all little to notice.

 

Agreed, you won't notice any difference with new spark plugs unless the old ones were in really bad shape. When was the last time you had all the fluids changed? 100K is usually a good time to take care of several things at once.

 

@ 107K miles...the old plugs could be worn. If they are then you'd notice something

had my full service done at 96k and didnt notice a thing....all fluids complete flush and plugs done, and the belts, car feels EXACTLY the same, still a beast as always

 

How much did it run you and where did you get it done?
