Brisk recommends the LGS for naturally aspirated or stock forced induction applications. If you're pushing lots of boost or have otherwise mod'd the system, they're pointing people to the Silver Racing.

... per a conversation I had with them.

Yes, Martin will always promote the top model. The supercharged Ford guys have been using the LGS series for years with superb results. Go one heat range colder than you think you ought to, and life is good.

Spark Plug cap seals

Is there any reason to change these, I haven't taken it apart to see if they are alright, but I am going to do the plugs and wanted to know if its worth the time and the cash to change the cap seals. This is what i am taking about:
