NGK (4589) IFR6T-11 Laser Iridium Spark Plug (8 Pack)

Just as expected.

Used these on a 2009 Toyota Matrix 2.4L AZ-FE, perfect fit, same length, same suggested gap already pre-set from factory.

Each plug came ready to install. Just be sure to torque them in properly.

The NGK (4589) IFR6T-11 Laser Iridium Spark Plugs are a fantastic choice for anyone looking to boost their vehicle’s performance. After installing these in my boat, I immediately noticed smoother idling, quicker starts, and improved throttle response. Overall, these spark plugs deliver high performance and reliability. Highly recommended for any performance enthusiast! 1999 Toyota Epic Lexus V8.

Just what Toyota suggested for the 06 Tundra. Got a little more pep and milage increased slightly.

I put these in my 2006 Toyota Tundra 4.7L V8 after having some misfiring issues. It turned out to be the ignition coil, but these spark plugs are running great and are reasonably priced. Much cheaper than paying for the dealership to replace and they're easy to install.

They work fine, just like any other spark plug. You can’t tell the difference when you’re driving between these and the original copper plugs that were OEM. These just lasted longer. With as easy as it is the access the plugs on my tundra, I should have gotten the $5 OEM. Maybe if yours are different to get to, you would want a longer lasting, iridium plug, but not for Tundra drivers. Save the money. Use the OEM plugs Toyota intended. They’re list in the manual NGK or Denso. You’re welcome.
