Changing Plugs
I've just passed 100,000 miles, and still have the original plugs in the engine. I think it's time for a change, and dealer pricing is out of sight... as well as an all day affair to drive 50 miles each way.
I'm sure somebody --- many bodies --- have changed their spark plugs. What brand of platinum plug is recommended, and how does one gain access to all 6 plugs? Is this a practical DIY project? Thanks in advance, Fred Robbins |

I saw a great "How-To" on this somewhere on the net or in here for that matter. I don't remember where it was?? I used it and I got my plugs changed in about forty minutes and a lot of patience! (and cusing!) It's definately a DIY project with all the right tools.
Many of us have chosen either NGK Iridiums or the Denso Iridiums. Both are great plugs. Check this link out: http://www.subaru-svx.net/forum/show...5&pagenumber=2 Last edited by JLittell; 07-29-2003 at 12:05 PM. |

Someone will pop in sooner or later. I can find it at my home later if no one can find the write-up. Once I do, Maybe Earl can add it to our "How-To" locker? Earl you awake today?

What are "iridiums" ? I remember NGK platinums, Lodge platinums, etc. Have I been asleep for too many years? Fred |

Iridiums are supposed to be 8 times stronger than platinum, 6 times harder, and with a melting point 1200 degrees higher. New laser welding techniques make it possible to make a spark plug with an iridium electrode. The result is a plug that requires less voltage to spark, burns more of the fuel in the cylinder, and can spark at LEANER air/fuel mixtures resulting in higher horsepower and better gas mileage. You do not have to gap these on the SVX!
Although the plugs are more expensive, you don't have to change them as often as garden variety spark plugs. The iridium electrode is extremely resistant to erosion, so it can last MUCH longer than a normal plug. (Longevity will vary by usage, fuel mixture, and other factors.) It's the ultimate spark plug. Available in stock heat range, or one range colder for high boost (18+ psi) race applications. |

i run iridiums.
just incase you never get the info you need, heres what i did. its not easy. youll need to remove the air filter and airbox. i have a cone and i just pushed it out of the way so im guessing youll need to. take out the batter if you want. youll need a socket wrench (ratchet) of course and a plug socket. i at some point needed two extensions. you might need a screwdriver. first thing to tackle is all the coils on one side. the black things covering the plugs. they are bolted in. i learned from someone to unscrew the bolt almost all the way, and use the last couple threads to catch the coil and pull it out. just yank them and they should pop out. move all the coils out of the way and get to the first plug. its in there deep and hard to feel around. i just dropped in the plug socket with the extension, then connected the ratchet. youll definitely have to do this on the farthest one in (plug on cyl #6). unless you want to use the access hole. i didnt do this because it was covered in some kind of hardened dirt that bonded to the plastic. >_< just have patience and try different things if you have to. the first time will always be the hardest but after that youll either always do it yourself, or never want to again. 0_o when you pull the plugs out make sure there is no tape. one of my boots was ripped and the last owner put tape on it and it was touching the plug, burning it. i just scraped it off because it was brittle and crusty. to put them in put one into the plug socket and just feel around. they almost fit horizontally. put them all in and put all the coils back on (with bolts, mine was missing one) and reconnect everything. good to go.

Changing Spark Plugs
Found it! Here's the link:
http://www.ryanmacdonald.com/car/howto/plug/plug.html Maybe Earl can can convert it to PFD Adobe add it to the How-to?? There's are few good other How-To's of his website! He did a great job with descriptions and pictures! Credit to Ryan if he's still around! |

Hi Guys! I just changed one side of my engine with Bosh Platinums last night and now my car is missing!? I won't idle very well and the engine sounds like some farm-equipment rather than an omni-potent flat 6 when going below 3000 rpm! Could have I over tighten the plugs? Or left them loose? Please help! I'm depressed!

I would pull them out and put one back in a a time. You might want to check to see if they are going in straight. Make sure your coils (boots) are pushing in correctly. Do not force them!

Thanks! That's what I fugured I'd try tonight. Should I try starting my engine with one plug out (or the boot)? That way I could find out which plug is causing the trouble, right? Man... it was so easy on my in-line four One more thing... I assumed those plugs came pre-gapped. I asked for SVX plugs in Auto Zone...

You don't have to gap the plugs on iridium and platinum plugs

I should have posted earlier, but I have a new how to on replacing the plugs in the How-To Locker. It gives the torque and checking the boots. Hope it will help out.
