I was thinking of getting my Denso spark plugs installed at the dealer when i bring them in for header install and sways. How much do places charge for this kind of install out of curiosity? Or am I better off doing this myself?

Do it yourself. I did. The most annoying thing is the strut bar. Once that was out of the way, thing was easy as pie.

 

where and how much where your denso plugs? also how much power gain, thanks
