50K miles = Time for Spark Plugs!
After getting the oil done this morning at the world famous Harix's in San Gabriel, I decided to try to change the plugs on my own. So, while I was in there, I took a few pics so the rest of you can decide if it's something you want to try.
First getting to them, a bit of a J O B. You need to remove the trunk carpet, net, and trim only to find the access panel basically glued on by double sided tape after you removed the bolts. A little tugging/prying, and it comes off.
Then, you'll notice a bracket over one of the coil packs? Yeah, because getting to them wasn't hard enough already. Luckily, the bracket comes off and goes back on very easily (I think it stabilizes/secures the intake plenum from what I could gather).
Once you get to them, process is fairly straight forward. I did them one at a time, hand tightened each, then added about an eighth to a quarter turn after that (too lazy to get a torque wrench out and check each one). While each coil pack was out, I cleaned them with an air compressor and cleaned all the contacts.
Overall, not a bad job and found the top three plugs actually harder (awkward reach) than the ones you get to from the trunk panel. Once that panel and the crazy surprise bracket came out, they were actually easier.
Oh yeah, almost forgot, changed my K&N air filter (I have two so I don't have to wait for it to dry when I scrub the heck out of it) while I was in there and checked on my Shorai which still looks brand new!
