Thread: Brisk LGS plugs my take on them.

A well respected member here told me Brisk has come out with a new LGS plug that has a tighter gap designed for turbo applications. I have these plugs, and am planning on putting them in this weekend. Hopefully the well respected member will jump in this thread with his findings, once he gets his set installed.

Currently I'm running AL 104's @.050. Out of all of the plugs I've tried, my car idles, excellerates best with the NGK TR6IX plugs. Obviously SOTP differences are quite subjective and not completely helpful.

If I do any real testing, is there anything anyone wants to know about that I can somehow document?

One thing to note. Upon visual inspection there is inconsistancy in the silver center electrode. I would have thought a plug designed like it is would need tighter tolerances, but that is just speculation at this point.

I have aquired these plugs from Lee, Thanks Lee , and I must say I am totally impressed with them so far! I only installed them today along with my PRJ 10.4 plug wires and the difference between my AL 104's and the LGS's in NIGHT and DAY!

Why?

Well so far, the performance of the engine in acceleration is almost seemless now as compared to my 104's. Idle in my car is smoother than before. I have yet to do a really good WOT run, but with the limited space I had in traffic, they performed WAY BETTER than I had hoped!

I am serious about the acceleration part. I noticed a difference almost immediately with them. There was no jerkiness in the steady increase in the gas to the motor as I had felt with the 104's. I almost couldnt tell I had shifted and power just seemed to keep coming until I realize I am almost doing 80mph heading into traffic

I will hopefully figure out the mileage thing, but my current tune is kinda jacked so it will not be an accurate account for these plugs, but on the performance scale they are TOPS so far in my book! I am nowhere as versed as Lee is in regards to these plugs, but from a pure drivers take on them, I can not see why anyone would not want to use them!

As for the heat ranges of these LGS plugs, that is something maybe Lee can answer or perhaps Overkill. But I definitely am enjoying them and plus with them being pure silver, they are gonna have atleast double the life of the 104's. And that is a plus in my book.

The LGS 14s are equivalent to roughly an NGK TR6 if memory serves me well.

I'm still enjoying my LGS-Ts! Having a much better experience with them versus the old regular 15s I tried before. They seem to have improved my mileage as well.
