Yesterday I had my new plugs installed at my dealer. I drove out of the lot and immediately noticed that the car was running smoother and accelerated better. Wow! Talk about a cheap mod!!! Has anybody else experienced this?

 

Smoother idling and less apt to stumble coming to a stop, especially with iridium plugs.

 

Are the new plugs installed according to the spark plug TSB iridium?

 

My tech explained to me as a "little hotter" plug.

 

No, they are still platinum. As far as anyone can tell, the new plugs are basically the same as the old plugs but with a slightly different crush ring. This new crush ring may not necessarily be by design or intent but simple a natural evolution of NGK spark plugs.

 

Nice butt dyno. I think it is in your head

You think the car will be smoother and quicker, but prolly not.

Yeah, it's probably me -- I CAN be called "old"! It sure felt smoother and quicker. Hmmmmmmmmm.

 

it seemed to me that the car was faster off the line with the new plugs, but less punch at vtec...
after a week with the plugs, its all back to normal again-

 

Nothing wrong with that! I'm familiar with that tune myself.
