Q45 Spark Plug Change
My 94 Q45t is comming up on the 100K miles mark and I am planning on changing the spark plugs myself. The local dealer wants $500 parts and labor to do this which sounds like this is a hard job (or at least a high profit one). I've changed lots of plugs in my time but don't want to get in over my head. How hard is this job and what are the pitfalls/tips to watch out for? I was planning on using OEM plugs or is there something better to consider?
Plugs are a three hour job with some mechanical skills. Budget a couple more for the first time.
Once you start, the process is pretty obvious. Do one side at a time, lable things as they come apart, use dielectric gease on electrical connections, and DON'T break the connectors going into the coils.
Use only NGK plugs and expect to pay anywhere from $7.50 to $12.00 each depending on your source.

Remove the whole harness at a time per side, don't try to do one at a time or you'll break the wires or connectors. For removing most of the coils, it's easier if you remove the silver brackets before your pull the coil/boot off the plug. Reverse that process to reinstall. All this is much easier than it sounds, go for it.

Didn't JT assume sponsorship of the Yahoo board? There is still life there, but the board doesn't work worth a damn.

There were many great Guru's and diehards there, but I think Dennis aka Q45tech was the heart and soul of it.I am SO glad we were able to convice him to come here for us.
