Lynn,
which spark plugs would be suitable for Turbo rotary in
aircraft?
Buly
The 93 twin turbo uses either the BUR7EQ (standard) or BUR7EQP (Platinum)
in leading.
The BRU9EQ (standard) or BRU9EQP (Platinum) in trailing.
The NGK site has pictures of each plug.
I could not find a heat range chart. The turbo plugs would be near the cold
end of the coldest range. Nice site but the explaination of detonation, and the
cause of the shock wave is incorrect.
