Which Spark Plug are you using on your Supercharged 100?

[hidesertfj40]

It is time to replace my plugs and my 100 has the factory TRD Supercharger. The TRD sticker under the hood says use: NGK BKR7EVX-11, and the TRD paperwork that came with my 100 says to use: NGK BKR7E-11.

I cannot find any posts on which one is correct or if either one supersedes the other...

What are you guys using?

Supercharged 100s are extremely rare. You might get more info posting on a Tundra forum? You've probably done a Google search so you know the first plug is iridium and the second plug is standard. All things being equal, I'd go with iridium plugs, but then my 100 breathes normally.

Design Symbols used in NGK Spark Plugs:

BK - Thread Size / Hex Size: 14 mm / 5/8" (16.0 mm) ISO Type

R - Resistor

Heat Rating Numbers : 7

E - Thread Reach: 19 mm (3/4")

VX - Firing End Construction: High Performance Platinum

11 - Spark GAP: 1.1 mm (.044")

The only difference between the two plugs you posted (NGK BKR7EVX-11 and NGK BKR7E-11) is the "VX" designation. The one with the VX is a high performance platinum construction.
