"I was sceptical about this new spark plug technology, but living in Albuquerque, home of Sandia Nat'l Labs, where the scientists invented this technolgy, I felt they were worth trying in my '05 Toyota Tacoma. When installed according to the instructions, the increase in power was immediately noticable, but not enough miles yet to prove gas mileage increase. But the power increase has made the Tacoma fun to drive again!" —William W from Rio Rancho, NM bought a Pulstar Performance Series Spark Plugs for a 1992 Nissan 240SX, 4.0L V6.
