spark plug pregunta
i was hesistant to start this thread but ive searched and didnt find a definitive answer... i called inline pro and they said to use ngk 4776's but no one carried them around here (norfolk). are these the plugs that everyone else uses? i need to replace mine soon so any help is appreciated.

I've gotten tons of life out of NGK Iridiums on my all-motor and boosted cars. boosted I would just run at least 1 heat range colder than stock.
I run BKR8EIX (NGK iridium 8 heat range)
