Spark Plug questions

[navbtcret]

So now that you changed the plugs would you recommend using dielectric grease on the boots and plug connectors?

I always put some dielectric grease in the boot every time I change plug. I also put a little anti seize on the threads of the plugs. Living in the northwest where we get crappy winters and a lot of salt on the roads I put anti seize on every bolt I take out of any vehicle prior to putting it back on.

I did anti seize on the spark plugs, since I always have some laying around. But I didn't do any dielectric grease.

Ive owned dozens of turbo cars (like  more than 50) and one constant Ive found that regardless of the make/model is that they 'eat plugs'. It seems to depend on the 'severity' of the tune and amount of boost. In my 2.2l Mopar track car if the plugs last 3K miles Im surprised 8) Street car at 16PSI of boost or less, 15K miles is when I check/change them. 60K miles you went? Not sure if we should congratulate you or dunn you for not doing em sooner Were any of them loose or have combustion 'tracing' up the side of the body?

Interesting observation and VERY short electrode life…. wonder if anyone can weigh in and explain why this would occur in turbo'd vehicles.

I think I am going make changing the plugs every 15,000 miles part of my maintenance program.

I did mine at 50k went with the upgraded 528s, prepping for another set with my tune upgrade and downpipes at (dare I say it) 100k!  If you're drag racing or autocrossing I HIGHLY recommend changing the PTU fluid in the front annually.

What is the PTU? Cost for the fluids?
Sorry to the OP for the mild threadjack.

Fancy name for the front diff, if you do a search there are a few threads on it.  If you need info shoot me a pm.

What condition were the electrodes at 50K miles?

 

[Night Hawk]

Pretty worn down seems the newer rev are the fine wire type similar to what I had in my 03 Cobra

 

[Kolk1]

I'll take full body pics of them tonight.

None of them were loose, None of them were stuck. All of them seemed to be torqued properly still.

Just got my plugs replaced with sp534 I tried to get the old ones but they threw them out. Feels smoother at start up and idle. Also seems to respond more confidently. Needed to get done they did charge me 300 for it though.

EEK!  I'm gonna call my shop tomorrow to see how much.  Then maybe bug another guy here to help me.

Yeah I have a check rear park aid on my dash. They check it out 950 to replace 2 of the sensors. I assumed it was covered under ESP warranty but apparently not.

I pulled my plugs and regapped them and reinstelled them in about an hour. It's super easy save your money !

 

[DJE624]

Has anyone figured out the difference between the 528 and 534?

My thoughts exactly, there is really only one plug that is kind of a pain to get at but not that hard, save your money and replace them yourselves.

Keep in mind for the spark to jump the gap of the plug, the center electrode or the wire HAS TO loose a tiny bit of itself. Microscopic yes but it adds up over millions of cycles. This process is easiest for the ignition system when ther are sharp edges on the electrode or wire, heck we used tonfile them or cut the end of the wire off with snips... I suppose its all relative tho, did you know that a top fuel dragster completly 'uses up' its plugs before the motor even turns over 1000 revolutions!!??

How could that be?  It wouldn't even start.

 

[SHOdded]

It would start, but plugs would get used up in every run, since the entire process would last only a few seconds.  If I understand the math.  :clown:
