I Bourght new plugs today for my 1600cc TP but they are NGK brand and i have heard sumthing bout not to use them because they go bad with allot heads or sumthink?

And i checked in the owners service manual and only bosch and champion was recomended??

Also whats the best leads to use?? or what do you find good?

From Dylan

Hi Dylan
NGK are OK ... same as Bosch..
I wouldn't use Champion in My lawn mower.. lol

Use never seize on the threads or Moly grease etc to stop the steel spark plugs from interaction with the alloy heads..

I've always done this, even with new cars and never had any problems with the spark plug threads..

Lee

What do you recomend lee?

hi again Dylan

the spark plug leads sold by most VW shops have wire in them
which was the original type of leads..
they don't burn out like carbon or silicon leads, or break..

I have broken the silicon inside NEW silicon spark plug leads just pulling the lead off the coil...
that is how fragile they are...

these leads are also the cheapest.. lol and the spark plug connectors are made to fit them

LEE

What do you mean by the spark pugs are made to fit them? Cause my spark plugs have the larker ands and they dont screw off

From Dylan

Hi Dylan use the Bosch W8AC the cap screws off and the thread length is correct,over the years we found that a few makes of plug extended into the cylinder and became clogged with carbon.when they were taken out the thread also came with them. I have a new set of original leads with the connectors and this will rectify your problem if you fit the Bosch plugs. Just pm if you want them. Les

why not platinum plugs?


Cheers!!

I believe NGK have a cut thread where Bosch and Beru have a rolled thread which is more correct for VW heads, also as stated above, preference is for copper leads with the resistive bakerlite plug cap. These are better for the hot environment and most importantly are matched to your 5k ohm distributor rotor to have the correct overall resistance. If using silicone leads, you should use a rotor with zero resistance.

I use Magnetti Marelli electronic ignition
that run through copper lead to dizzy
silicone leads to the NGK plugs

I use silicone leads because they're blue
also I use NGK BP5HS or something
because bosch W8AC were obsolete at the shop I went to when I bought it.

Hey Dylan, did the responses answer your questions? how did you go getting the plugs and leads to fit and function?
Thanks
Jason
