HI,
i have Panchito 044™ (40 x 35.5) head with megaspark 2.for my 2110cc.

what kind of spark plugs do you recommend? for this

Fri Mar 27, 2020 7:04 am

12mm 3/4” Reach Spark Plug. I use NGK

NGK D9EA Spark Plug, 12 x 3/4" Reach Threads, Conventional Tip, 11/16" Socket is a regular tip spark plug, suitable for VW engines. Regular tips are less expensive and give piston clearance that can be a problem with projected tips. This plug is the correct heat range for HOT engines, since it's 2 steps colder than stock.

On advice from CB Performance, I’m using DP8EA-9 plugs in 044 SuperMags on a 2276 with a Pertronix 2 kit in an 094 distributor.

NGK "9" is 4 steps colder than stock. Stock heat range in NGK is "5".

anyone know the Iridium ngk for the 044's?

My fresh 1835, (only 200 miles), is running nicely on the NGK D6EA. They're only $2.49 apiece at flaps. 12mm x .750 in.

Apparently, spark plug heat range is another alien science.
I did a little reading on the subject but I’m still clueless on how to determine ones need.

The untold story, how to read plugs correctly. I was fortunate enough to be around when reading plugs was how we tuned AFR and set timing. If you read on the Motorcraft spark plug site you will find pages of great information.
One thing to always remember reading a plug, is to find an open area with a good straight area. Install your new plugs. Make a pass and shut of the ignition just before you lift the go peddle. This will keep the plug from showing any false readings. Remove and inspect plugs. don't forget to read the timing mark on the ground strap. Plugs will tell the truth and nothing but the truth.
Some of this will be mute do to having AFR sensors. (I do miss the old days a bit. The cops would ask what I was doing and I would reply. "Reading plugs of course, I thought that was evident")
The engine will tell you what it wants. Cold will foul and hot will cause pre-ignition. Lots of people struggle to tune with the wrong plugs. It is a balance between jetting,timing and plugs. That being said if you have mismatched parts( incorrect build) such as to big a carb, incorrect cam ect. You will find yourself spinning your wheels.

For the $200.00 it cost to buy a AFR Gauge/sensor combo it's not worth pulling hot plugs out of an engine and either burning your fingers or buggering the threads.
That and since the gasoline nowadays is nothing like it used to be who can say what an ideal plug looks like.

That -9 is some other feature. His plugs are 8, which is still really cold. Most aren't running the needed compression for such a plug.

It depends on cylinder pressure. When I called NGK they could only site various cars' static cr as examples. Static doesn't matter. A stone stock engine on 9.5:1 cr would need colder plugs than a 2332 with a FK89 on 10.5:1. If you use a dynamic compression calculator you can more or less determine what kind of plug to use. If you have over 7.5:1 DCR you'll be fine with a 7 heat range. At 8.0:1 DCR or higher a 8 heat range might be more suitable. Anything less than 7.5, use a 6 or 5. I use 5s on my stocker.

That "-9 " is the gap as delivered, in this case 0.9 mm.

You meanie... Don't screw with these guys. The -9 means 0.035" :D

On that engine, I had a Scat C-45 cam on a 2110cc (90.5 X 82) That was 15 years ago but if I remember correctly it had a 10.5 static CR and I used NGK DP8EA-9 (not D9EA as I posted before :oops:)

I'm doing a 'refresh' on that engine now with a WebCam-218, 2180cc (92 X 82) and new MoFoCo heads. Haven't gotten around to CR calculations but it has 14mm plugs I'll have to come up with another plug and heat range.

The old heads are off. I'll take a photo of the plugs, that have always had a tan center electrode.

As for one of those numbers on the plug being the 'gap', I don't know, since my igintion system is completely stock I use the stock 'gap' .024

You're right. Give them an inch, they'll take...oh, never mind...

He originally quoted "D9EA" which is in fact a 9 heat range. The "-9" is the preset gap of the plug.

Then someone else mentioned an 8 heat range, and it started getting confusing.

I would guess it would depend on what coil you are using.

I run a ford coil.

And these. But my heads are long and large thread. Just some info.
