When was the last time you changed the plugs in your fc?

I hadn't changed the ones in the s5 for quite a while and started to notice a very rough idle, random stalling, down on power up top. Thought it was due to vacuum leaks or something else.

Pulled the leading plugs and they were toast. Massive amounts of buildup and other junk. Put in a fresh set of leading and wow. Feels like a different car.

So if you got the time/money pull the plugs and replace them. It definitely made a huge improvement on my s5 gxl

 

should be a no brainer

 

Thanks for the reminder!

 

point in case...

Gosh Ben just trying to make the guy feel good.

 

damn!..and I changed my Engine and kept the plugs!
(plugs change every 5 oil changes).

 

yea my car eats plugs prettty quick need a good tune. Anyway wanted to go 9s for the better heat range and are these platnium plugs better? I can almost get the platniums for the same as coppers but seeing if anyones switched and saw better life expectancy for the most part.
