My son just bought a '94 Nissan 240 sx 2.4L, 150k miles. I told him to service the car and start from scratch. I recommend with that many miles to use hotter plugs. However I'm not sure if hotter plugs are longer and might cause any kind of internal clearance problems with this car? What about Platinum plugs, are they good for high mileage cars?
