aigochamaloh Posted November 3, 2012 Share Posted November 3, 2012 I finally got around to changing my original spark plugs at 78k miles. I wasn't getting any CELs or noticeable hesitation during acceleration, but I figured, it was time since I was way past the service interval of 30k miles. The job only took roughly 30 minutes. Not bad at all! I read through GEE-OTTO's tutorial here. http://legacygt.com/forums/showthread.php/2-5i-spark-plug-tutorial-117769.html?t=117769&highlight=spark+plug I only needed the 5/8 spark plug socket, two 3" extensions, and my ratcheting wrench. I took off the snorkel and airbox to gain access to the left side, and it was very easy from there. The battery side is a little tighter, but you do not have to remove a single thing. There is still plenty of room to fit the two 3" extensions and the wrench in there. Here are what my plugs looked like at 78k miles. They are ordered on the paper towel the same way the engine is oriented when you look in from the front. https://www.dropbox.com/s/uzpxmj5cv7y6mgf/2012-11-03%2016.31.55-1.jpg 3 4 1 2 Cylinder 2 and 3's plugs don't look worn a single bit, but cylinder 1 and 4 have worn down quite a bit. Interesting. Car is noticeably more peppy and responsive though, even though I said there was no noticeable hesitation before. I really question changing them every 30k miles though. That seems excessive considering these are laser platinum plugs. Link to comment Share on other sites More sharing options...
GEE-OTTO Posted November 4, 2012 Share Posted November 4, 2012 I recently changed mine out and i didnt have my 3" extension...... i tried for 30 mins to get at No 4 using a combo of 8 and 6 inch extension to no avail Had to run down to AutoZone and buy one. Good to see you saving yourself $$$ buy performing this routine service yourself! Link to comment Share on other sites More sharing options...
aigochamaloh Posted November 5, 2012 Author Share Posted November 5, 2012 Hahaha seriously, two 3" extensions is all you need. And I wouldn't take it into the dealership just for that and get ripped off. I'm someone who does engine swaps in the garage! Link to comment Share on other sites More sharing options...
cortman Posted November 6, 2012 Share Posted November 6, 2012 They recommend changing them every 30k because that's a safe estimate of the plugs effective lifespan. I know Dodge recommends every 30k as well. Don't some manufacturer's have longer service periods? Link to comment Share on other sites More sharing options...

Camrys suggest you check them at 60K and change them at 90K or at least that is what the dealer told me:redface: Link to comment Share on other sites More sharing options...
cortman Posted November 9, 2012 Share Posted November 9, 2012 That's why I don't drive a Toyota, you never get to work on them:) Well, there may be other reasons too... Link to comment Share on other sites More sharing options...
Stubeck Posted November 14, 2012 Share Posted November 14, 2012 My cars have previously said change them at something crazy like 110k. Link to comment Share on other sites More sharing options...
NickB34 Posted November 15, 2012 Share Posted November 15, 2012 I did this for the first time last night, took about 45 mins. It's definitely tight near the battery, but two 3" extensions did the job. Link to comment Share on other sites More sharing options...
