Spark Plug Life
Recently, my idle has gotten a little rough on my 99 FRC. It has also shown a decrease in gas mileage from about 22.5 average to about 17.9 average in the last 4 months. I don't know if I have original plugs as I bought it at 15k miles, but it now has 28k and I am thinking about the new fancy 4 point platinum plugs. Anyone have any experiences with plugs? Also, is swapping plugs an all day job like it was in my 99 camaro?

I replaced my stock plugs with NGK TR55IX plugs. It took me about 2 hours but it would have been faster if I had taken the coil pack and air injector tube off first thing. (They block access to plug 7)
