^ Thats a good thing SBS! not saying he 534 is a bad option but they're made to run a .044 gap

id rather run a plug that's designed to run a small gap like we need and won't spread out as much over time.

542s also seem to be cheaper and require a lot less adjustment of the gap before installing.

The SP-534 come pregapped from the factory at .030....

My mistake it must be the NGKs that come with the larger gap?
so as it stands the 542's are one heat range cooler than the 534s.
both viable options

I assume these are colder plugs than stock?

IIRC the 534 is the stock heat range, the 542s are one range cooler.

 

[8nutz8]

yeah 534 is stock for 13+ and 542s are one step colder

That confuses me.  SBS runs higher boost than me,  would he not be on colder plugs?

Why would he have to be?

Ok more confusion..  did that change?  I SWEAR it has been beaten into me i needed colder plugs to offset pre-ignition ...

So really serious what plugs should i be on for a non-meth 15 or 14.5 pound tune?  i am so confused ..

 

[SHOdded]

Really, no need to spend so much time on so minor an item.  Put in sp534 plugs.  Done.

Spark plugs are a supporting mod just like downpipes, filters, exhaust and so on....Are they essential, no.

Yes some people and companies would have you believe they are essential...Colder plugs help extract heat from the combustion chamber which may help in reduce preignition....Higher octane fuel is the best means to help with that condition.

I ran the dog crap out of my SHO and had 22k on the stock plugs with countless 20 psi runs on 93 octane fuel....

ok,  well then i will replace the plugs after looking at the connectors to the ECU. 

AJP,  what would a blowout look like to you on the logs?  anything at all ?

Any special tools needed to remove the cowl to inspect the water logged exposed to air rain mud snow washer fluid pressure washers ECU?

*stupidest place for a ECU*

To be 100% fair here.. I only know of one thread where someone had an ECU go bad...

You need a wiper arm puller.

I just did the front three plugs.. pictures incoming .. but they are not good.  i will check the ecu .. but not before i do the back three.  there done.

 

[8nutz8]

gap really spread out? i had a hunch

Here are the front 3.  Top is left front cylinder, then middle is middle cylinder and bottom is right cylinder.

Note the hideous carbon baked into the insulator.  these plugs were running too cold.

I did not check the gap.  I will when i get home .. but with this thick of carbon i'm shocked it has not been misfiring bad enough to log it.

 

[8nutz8]

any oil consumption issues?
