Thread: Pulled my spark plugs out today....have a look

These are/were Brisk LGS (Silver tipped) plugs I have had in my car for a little over 2 years now, they probably have about 50k miles on them. The tips were not bashed in or anything, but there is discoloration on them and a few have what appear oil marks on the threads, maybe you all can tell me?

The top set of plugs sitting on the box are from the rear bank in order from left to right, and the bottom half are from the front.

Any thoughts or input would be greatly appreciated.

I have never seen that style of plug.

They look ok, but I must say cheap plug FTW!

Slight browning with little to no deposits means just right.

exactly what i thought

I say replace them with something better...like COPPER PLUGS

How the hell are you supposed to gap those?

104s replaced them

I got worried after I finished up putting in all the plugs, I started it and everything seemed to run fine, then I saw some smoke come from the rear manifolds. I was like ! I thought maybe one of the plug wires was resting on one of the header tubes or something else. I started looking around and couldnt find anything.

Then I remember when we first installed the headers over a year ago, they smoked cause of the oil on our hands when we were positioning the headers. The heat from the mani's through the header tubes heated up the oils that were on the tubes from me touching them.

At least that is what I hope it was I checked all the wiring and the upper manifold O2 sensor cable to make sure everything was not touching the manifolds, same goes for the plug wires and the rubber boots.

I hope that was it

What? They are no bigger than any other plug...they are just 4 prongs at the tip vs. 1.

Weird looking plugs

I have Brisk plugs in my coupe. Those are awesome.
