Sparkplugs!!! Not Bosch! Only Champion.

For these of you having fun with Bosch spark plugs:

Bosch plugs are weird - I had my wires and plugs replaced recently and still the car had some moments I would say it's fouling a little bit.

Today I finally dumped my second set of new fouling Bosch sparkplug set.

I put in the Champion Copper Plus 302 (N11YC) and my car drives stronger and noticeably smoother.

No more Bosch!!!

I recommend Champions to anyone here.
I gapped mine 0.34 inch. I am indeed very surprised.
The difference is HUGE.

And the cost is $1.19 EACH. It is so cheap!
