changed the plugs on the 8 today
plugs have been overdue and because of the snow and cold, i haven't been motivated to change the plugs in m7 05 RX-8. today was nice so i decided to slide out and get it done. a completely different beast than my FB in plug changing procedeure. i found that the best way to change the plugs was to jack the car up and remove the let front tire. from there you can access the front rotor's plugs with a couple long extensions. the rear rotor's plugs can be had from underneath very easially. bear in mind that these were the original plugs with 37K miles on them and the engine was still running well. i did however notice a decrease in fuel mileage and hoping the new plugs will help slightly. i used the oem laser iridum NGK RE9B and RE7C plugs. here are the pics:

those plugs look great, you should see some of the plugs that come out of the rx8s.... they make it look like the combustion chamber is not a nice place to be.
i really like the Rx8 plugs though, they are a better design than the FC/FD plugs
and wow, ohio does a number on cars... in CA all of our rx8s are still shiny on the bottom

ohio is an awful place to own a car. hands down ruins cars from the road salt. the underside was already pretty foul when i bought the car. i don't drive it in the snow and i don't drive it when i know the street departments are salting. it does collect road spray which has that nasty salt.. the car came from michigan and was driven year round (in the salt i would guess) for two years before i got the car.. i'll start a por 15 treatment this summer and start replacing the rusty parts with new parts to prevent failure and leakage from rust. this is the reason i was saying in another post that Wacky made about cutting up a perfectly good CA driven and owned FB that it was insane to cut up a perfectly good chassis. in OH we dont get to pick nice rust free 7's. i have an 85 GSL that came from FL thats super clean with zero rust. i keep that car in a garage year round.

On the other hand, we Cali guys get heartsick at having to consider parting with a near-perfect car just because the smog ***** won't admit to the reality of NLA smog parts for 30-year-old cars.
Gets me in a rage every two years, having to deal with that crap.

CA is terrible for their smog regulations and because of that i think they push perfectly good cars away from their owners. in ohio, after 25 years a vehicle no longer requires a smog inspection and tehre are only six counties in ohio that require a smog inspection at all.

So the older cars are a large, easy target to shoot at. Add in the abundance of tree huggers and the Green Technology trend and it becomes clear. Now...with smog equipment for the old stuff NLA new and hard to find used, it creates quite the conundrum. How do you smog it if your smog parts are broken? That's where CA's car retirement program comes in. They'll give us a few hundred bucks to retire the car.
