m112 c320 spark plugs change

Hi

Just quick question

Do I need dielectric or/and anti-size?

 

[grober]

Have read somewhere the new iridium NGK's have coated threads to obviate the need for anti-seize? http://www.ngksparkplugs.com/pdf/tb-0630111antisieze.pdf

We always use a bit of anti sieze on the threads. It works wonders!
And don't forget to check those plug gaps before fitting!!!!

Now that I have said that these new plugs are good for 60,000 miles some folks advocate taking them out at least once during that time simply to stop the chances of them seizing in the head!

I had no trouble in mine at 50k miles and never been out before, again a hard question

IF YOU FEEL YOU NEED TO USE GREASE this would do http://cpc.farnell.com/servisol/200002000-50gm/silicone-grease-tube-50g/dp/SASILGRSETUBE
available from maplins or amazon also------- use very sparingly!

Hi

Finnaly winter is end so i managed to replace plugs. Just want to share experience.

Job took me 2 1/2 hours. It wasn't too bad. The hardest bit was last 5th and 6th cylinder due to lack of room but getting different bits and extensions all is done.

Malcolm your "wire puller tool" is amazing. I got it made as you said and it worked wonders. No hassle no pain,perfect tool.

Old plugs did 8years and 30k miles but looked stone dry.

Car runs fine, better response on low revs range and no more rough vibrations!

Ps i will upload some pictures later

Thanks!
