Title: Replacements for 2004 Toyota Tundra Limited Double Cab V8
Review: I got a used Tundra last year (Oct 2010) and the plugs had never been replaced at 50k miles so i opted for these NGK Iridiums. I always buy NGK since i've never had a problem with them and these have been great, no problems.Hopefully the longer life and more precise spark justifies the additional expense, but really, since you only have to replace spark plugs very infrequently anyway why not go with a higher end plug (seriously, 8 of these plugs cost less than a tank of gas in this truck so why not).These were pre-gapped and i did not have to change them at all after measuring each one. The old plugs were well worn and way out of gap spec. The engine ran fine before and i had not yet started logging my gas mileage since i only had it for a month before changing plugs so i don't know if i've gotten better MPG or power out of these but they sure couldn't hurt. Engine has run like a top for the past year.
Is the review positive or negative?
