Any 2056 owners using stock FI?
What spark plugs are you using?

Update to this post:
Two of the spark plug holes(one on each side of the engine) in my new cylinder heads don't line up with the engine tin holes. I am not able to get the spark plug socket on the spark plug unless the spark plug is already installed. I am also not able to remove the spark plug all the way out without jamming the socket against the tin.

Option 1: make the freshly powder coated engine tin holes larger to accommodate the stock NGK 13/16" hex spark plugs. These have a 1mm protrusion.

Option 2: use NGK 5/8" hex spark plugs. These have a 3mm protrusion. Will this be an issue?

Other options?

Thanks

I'd stick with the NGK's. If you run rich go with the BR5ES (one step hotter).

So +1 for NGK BR6ES

NGK BP6ET

NGK BP6ES

I like the BR5ES. They seem to run a little cleaner being one range hotter.

Running BP6ET in my 2056, although i was told by several engine builders inclunding mine they will go to a 7 if running in the summer in a hot region like ours as the 7’s are a step cooler, last time i did a plug check they were prefect after running 1500 miles from last fall winter and spring plugs were about perfect . i hardly drove this summer so i didn’t switch. run them for a few hundred miles and check them.

Does the heat rating depend on the spark plugs gap ? Should, say a 2056 use a different plug than a stick engine ?

depends on a lot of factors, like my builder and other mechanics dont like the resistor plugs he says they run hotter, run low resistance wires,, and a non resistor plug, 6 seems to be sweet spot, my motor is higher compression running higher octane, but i look at the plug, and my AF , if i was running richer, i might run a hotter plug(5) but the 6 seems perfect judging by what i see on the plug, but also he says run a 7 in summer heat , cooler plug helps maybe a bit with higher head temps we see on the 2.1 builds and even stock 2.0's. the Bosch plugs i ran on my original motor when i got the car wwere the W7's. . lots of factors but right now, im staying iwth the BR6ET's.

I run these with a twin carbed 2056 (mild cam) she runs great, except when cold. Color is spot on

Another +1 for NGK BR6ES plugs. Run great with stock injection up here in the PNW, both L-jet and D-jet.

BP6ES.... or BPR6ES if you get noise in your radio.

What radio do you speak of? Oh. The dial thing. Perhaps yes, but when driving I cannot hear it. Plus, I am too old.

I turned mine on the other day for the first time in about 5 years. But I didn't listen to the radio. I used it to amplify the Google maps voice giving me directions.

Are you running the 2.0 or 1.7/1.8 plug location? Heard a lot of good things from Vanagon owners about the ETs so bought a box and switched my van over to them recently. Was thinking about trying them in my 1.7 as I read the plug design accomplishes an unshrouding of the spark similar to the 2.0 plug relocation.

new 2.0 heads , stock 2.0 plug location, so i cant comment on the 1.7 , 2.0 differences. i guess i can see the thought process of having that longer , not sure how that works out in reality.
