Can you even use stock tune with the C&L in there? Doesnt it require a tune?
Could be spark plugs - haven't changed those yet.

May as well change them if they are bad (I'll look tomorrow). If I do change them do those one expensive spark plugs really make a difference or is that just marketing BS?

My car has around 60K miles on it - bought it with 20k and warranty almost two years ago

Yes.... you can Max. I've done it for years ^^^ with my K&N CIA.

These are the top 2 imo (really good and not expensive):
NGK-TR55 or Autolite 764 copper core.

Wow... thats alot. And i thought 52K was alot and i drive the heck out of my car. Guess not as much as you.

NO, the C&L will throw a CEL. Don't run the C&L with the stock tune, you'll run lean. If you wanna go back to stock to try things that way, put the stock airbox back on.

Order the new tunes, before you load them on the device, put the stock tune on the car. But dont drive it that way. Once the car is stock, load the new tunes on the device, then load them on the car.

YOU CAN'T RUN THE C&L WITH THE STOCK TUNE!!
