Animalz Posted October 23, 2012 Share Posted October 23, 2012 I bought my 05 LGT in July and I'm going to change the plugs and wires. But I realized u have individual coil packs. What all do I need to complete the job? Do I need all new coil packs or do I just change the plugs? Is there a sertain kind of plugs I need? I am new to individual coil packs and Subaru lol so any info/ advice/ just help you can give will be a big help! Thanks Link to comment Share on other sites More sharing options...

AZP Installs Posted October 28, 2012 Share Posted October 28, 2012 On cars with the coilpacks there is no reason to change them unless you are having issues. Just change the plugs every 60k miles. -Mike Paisan http://www.pbase.com/paisan/image/91072632.jpg http://www.pbase.com/paisan/image/145749898/original.jpg http://www.pbase.com/paisan/image/133406601.jpg http://www.whiteline.com.au/images/logos/perf1.jpg 11+ Years Maintaining, Modifying and Educating TriState Subaru Enthusiasts.

With that said, if you are having an issue, move the offending (misfiring which you can find out from a CEL code reader) coil pack to a different cylinder. If the CEL code moves, with it then you have a bad coil pack, if not then you may have a bad cylinder or bad injector or bad plug (although I would change/check plugs prior to moving a coil pack). -Mike Paisan http://www.pbase.com/paisan/image/91072632.jpg http://www.pbase.com/paisan/image/145749898/original.jpg http://www.pbase.com/paisan/image/133406601.jpg http://www.whiteline.com.au/images/logos/perf1.jpg 11+ Years Maintaining, Modifying and Educating TriState Subaru Enthusiasts.

Max Capacity Posted November 12, 2012 Share Posted November 12, 2012 Use NGK plugs, you can get them from some of the vendors on here. Ask Mike at AZP if he can ship them to you. Fred Beans is another good source. Check the Vendor up top. 305,600miles 5/2012 ej257 short block, 8/2011 installed VF52 turbo, @20.8psi, 280whp, 300ftlbs. (SOLD). CHECK your oil, these cars use it.

UTwrestler22 Posted November 12, 2012 Share Posted November 12, 2012 Go to oreilly or autozone and have them look up what plugs you need. 25 bucks or less, done. You don't need vendors for spark plugs. And just so you know, these plugs are a bitch so lay aside at least 2 hours sense it is your first time doing them. Another tip, when pulling the coil pack off, unscrew it then turn it upside down. It pops out much easier. Especially that drivers side further back one. Also, put the 5/8 spark plug socket in first, then ratchet adapter then ratchet (you will need a newer flatter one for the back plugs on both sides) Like this:http://www.sears.com/craftsman-3-8-in-drive-quick-release-teardrop-ratchet/p-00944808000P?prdNo=3&blockNo=3&blockType=G3 Notice how it is flat and not round big and bulky like the older style. Use dielectric grease and i leave you with the walkthrough with pics: http://legacygt.com/forums/showthread.php/spark-plug-install-instructions-12070.html?t=12070&highlight=spark+plug+installation Link to comment Share on other sites More sharing options...

I've seen sooo many of them hand out the incorrect ones to clients of ours. -Mike Paisan http://www.pbase.com/paisan/image/91072632.jpg http://www.pbase.com/paisan/image/145749898/original.jpg http://www.pbase.com/paisan/image/133406601.jpg http://www.whiteline.com.au/images/logos/perf1.jpg 11+ Years Maintaining, Modifying and Educating TriState Subaru Enthusiasts.
