bp6es: 14mm, 3/4" reach, 13/16" hex, gasket seat, JIS height, projected tip

bkr6e: 14mm, 3/4" reach, 5/8" hex, gasket seat, ISO length, projected tip, resistor, V-power (v-grooved center electrode)

That all came from NGK.com

According to the NGK website the bp6es will not fit in a 1.8T engine, but the bkr6e will.

According to the NGK part number PDF:


Thread diam = 14mm
Construction = Projected insulator
Thread Reach = 19mm (3/4")
Firing End = 2.5mm center electrode


Thread diam = 14mm
Construction = 5/8" Hex with ISO projected tip
Thread Reach = 19mm (3/4")
Firing End = 1.5mm center electrode with V-groove

There is a possiblilty that the 2.5mm center electrode may provide a better spark area but, I've always used the BKR6E because the stock NGK plug is the BKUR6ET. That is a tri-ground plug.

If you drop the triple ground design, you end up with a BKR6E.

Here's the PDF file with the number scheme:
