This gonna give you 30 horses

[diegom6]

Because it's special and got 3 holes on it..each made to develop 10 HP, so maths are simple, x 3 = 30!

Was checking for some stuff in my warehouse and found these spark plugs, it caight my attention and I'm lazy to find out for what engine was made...they are NGK, bot the misterous it's the left one of corse...

A little spark shield - nice.

[W1ccaboy]

I have never seen nor heard of anything like that before....... interesting

sweet 30HP each plug? so 30x4=120

im gonna be pushing 280+hp on a stock 2.3l s14..... for what less then $30 ??? ;)

[Hick]

pfft ill put in on an M20 and get 300hp

[Aptyp]

find out what they fit, cross ref. the numbers. Interested to find out.

[diegom6]

I have the code...just wanted to see if someone recognize it before let the world know the code:D

[moatilliatta]

those are wild.

[submwar]

weird. think you could stroke it out to maybe 12hp/hole?

IMO, more surface area for gunk to collect

[e30s52]

what is the part number?

[Jaygo333]

Where we get, me wanty baddy>:)

[moatilliatta]

maybe for a m106

My M42 had those plugs when I got it, but I think they were stamped Bosch. The recommended NGKs run better.

[uofom3]

Shit, I'd try them (and not for massive hp increase purposes)

i have a feeling those plugs are race only...the plug on the right we use in our 911s for high horsepower or high compression use (usually twin plug heads). We have a variant of the right one with 3 prongs, used in our 12.5:1 GT3 RS engine...and that car makes 500whp.

The one on the left I would assume would also be the same setup?

It would be really cool to run the plugs, but due to the fact the one on the left isnt made anymore, I would just keep them to show em off to my friends! lol.
