NGK Plug
Good day everyone... Does anyone know if a NGK Spark Plug exists that is the same as the NGK R5673-8, but in a Resistor plug? They are for 6X heads, and need to be 5/8" wrench, .460" reach, tapered seat, perferably "Non-Projected" tip. The engine is a 461 with a single SXE480 billet turbo making maybe 800+hp with 10-15 lbs of boost. 100% street car on pump gas. I will be running the Holley XFlow 1375 EFI, and it recommends "Resistor" plugs to keep RFI problems in check. I think the heat range of the R5673-8 would work great for me, but I need it to be a "Resistor" plug. Anybody have a recommendation for a part number? Thank You

Subscribed, cause I'm having trouble finding non projected tip, resistor NGK's as well. Different application though... Hope you find what your looking for.

I guess NGK tech is saying a "4" heat range would've been stock? I run a "6" heat range (BKR6E, for an edelbrock head) normally aspirated. And I don't disagree with the projected tip for normal driving. Mine are as well. But I was hoping to find a non to try as well. Same deal as you, electronics that won't tolerate noise.

I use the extended or projected electrode in all my 2-stroke MX bikes since the '70's. High revving 2-strokes are brutal on plugs.
The electrode actually runs cooler as it is the the direct path of the air/fuel mixture, as opposed to the "shrouded" (regular) electrode. Another advantage is more efficient burn with the electrode extended further in the combustion chamber.
