Installed my denso plugs (first time doing plugs on the Stinger) - took 2.5-3 hours. Found gaps of 0.024 to 0.032 on OEM plugs (measured 3 or 4 of 'em). Wow, talk about bad quality control. My knees are SO sore from leaning over the car.
I had to try 2 or 3 different ways to access almost every coilpack screw. Long extension, wobble extension, short/small ratchet, box/crescent wrench. Since I read ahead and got the swivel magnetic plug, and had a u-joint, removing/replacing the actual plugs was like 1/4 of the time at most. Getting the coil packs loose and off was SUCH a pain!
I don't remember doing the plugs on my Subaru EJ255/257 being any worse.. Maybe there is some truth to Subaru keeping backyard mechanics in mind when they design their cars. This could have been SO much easier if the coilpack screws had been moved over like 1/4 to 1/2 an inch in the right direction. Seriously, a small adjustment to the hardest screws could easily knock 30-40% off the time.
Started the car up, idled for 2-3 minutes, revved to 2500-3000 a couple of times, idle started dropping to under 1000, seemed totally smooth, no CELs, so I'm hoping it's all good. jb4 goes in tomorrow, and maybe DIY intakes as well..
