I found these plugs at my shop.
Can I use them in my 110 PG?
Thanks,
Tom

5's do work good in a naturally aspirated engine...6's are better.

Used 7's in my turbocharged racecar and Dwight uses 9's in his.

No more than the 6's recommended in anything on the street.

With NGKs a lower number is a hotter plug.
I use BR6HS 3922 in 102,110,140,150 and 180 Like AC44.
I might use BR5HS in a 80 or 95 like AC46.
