🔥 NGK 4904 Spark Plug - Pack of 4 (Improved SEO) Review

Replaced existing identical spark plugs, noticed improved fuel economy and performance. It's amazing how you don't realize corks wear out.

Don't change spark plugs in a hot garage or you'll be on the nightly news. First time I changed the spark plugs on my Sequoia and it took about 2 hours. I drove about 20 minutes, the control did not light up, started the engine and responded well. While parked the RPM dropped about 100. MPG is about 17.5 and will try to update later if there are any changes.

These spark plugs are great! They are pre-sewn. just screw it on and forget about it for 100,000 km. Put them on my 2015 Tacoma 4.0L V6. A small but significant improvement over stock plugs with 30,000 miles on them. I have a 6 speed manual and it's easier to slam out of 2nd gear, the engine doesn't jerk or jerk and acceleration from traffic lights feels a little springier. As a note. I have also fitted NGK Laser Iridium spark plugs to my Bandit 1250 4 cylinder motorcycle with the same results.
