So is this an electrical forum question, or an engine forum question....oh well

So I've always wondered...what's the best plugs anyway...and how about Splitfires??

(oh yah....L24:D )

well, the fancy schmancy plugs will work in your old z, but i don't really recommend spending extra money to get the expensive split fire, or platinum, or any of that crap. the old z wasn't really designed to take advantage of that, and it will not help any. i bought my z, which had platinum plugs/split fire, and it really doesn't do jack, though i'm sure it wouldn't hurt to put some in! i'd personally save myself a few bucks, and go with the classics.

Save your money on the Splitfires, I used them and saw absolutely no difference between them and just a set of NGK's. You might want to use a set of the resistor plugs so that you don't have to worry about any radio interference.

Who listens to the radio anymore???

Never know, traffic reports can be helpful at times. :tapemouth

My 74 came with splitfires- they work fine, but as i say, theycame in it from the PO. My 73 I use NGK's, and they're everybit as good as the splits, IMO. I had used Champion & Autolites in the 73 before, but they seemed to foul more than they should. Jeremiah

Since i've had my Z NGK's have always been the recommended plug by Zheads. I was told that since electricity always goes through the path of least resistance only one of the split fire electrodes is used at anyone time anyway.
