New plugs & ZZP 10.5mm wires

Running fine but had around 100K on the plugs with original wires.
Bought some new Iridium plugs 41-101's and a set of ZZP 10.5mm wires.
Third set of plugs at 182900 miles. The plugs I took out looked great and all were still @0.060".
Those back three pugs are a bitch...

That oil cap is nifty.

The 41-101s no kidding will go 100,000 miles.  So will the equivalent Champions and then some.

Not so much the Autolite iridiums.  The first set of those I had were done at around 60. I was so disgusted I did not even ask them to honor the warranty.

I am now past 395000 miles - time to think about plugs I guess.  

For the rest of you reading this:  The back 3 plugs are not so bad if (1) you use a single wobble extension, spark plug socket,  and ratchet wrench (2) your motor mounts are good.  When the mounts are weak the motor can rock back and make them harder to reach.  Alternatively, go after them from underneath (just roll up on any ramps, I have plastic ones I got from a department store ages ago).  If you have not tried going at the rear plugs from underneath, you will be surprised at how easily they are reached... at least I find it easy although I have to check myself that I am turning the wrench the right direction.

That looks like a totally neat one!
