airhound Posted October 28, 2021 Report Share Posted October 28, 2021 Thanks Roger, is the resistor a IC anti-noise related feature? Errr….. Quote Link to comment Share on other sites More sharing options...
Anticept Posted October 28, 2021 Report Share Posted October 28, 2021 That's what it's for, at least originally when resistor plugs came out. These days it's important to use resistor plugs if your engine is designed for them, as they can have an effect on timing accuracy. It's actually quite hard to find non resistor plugs anymore anyways, they're pretty niche. Quote Link to comment Share on other sites More sharing options...

I went ahead and bought four. I needed to replace some ones I've used. Amazon used to be a place to buy them, but the prices have all gone up.

Tom Baker Posted March 18 Report Share Posted March 18 I had tried to order some from Amazon. After having the shipping pushed back a couple times, and waiting for over six months they finally just cancelled my order. Quote Link to comment Share on other sites More sharing options...
