Review on Denso K16TR11 Traditional Spark Plug by Noah Warneking

Matching spark plug for any Toyota 3.4L 5vz-fe engine. This happened with the 1999 4Runner Sport and also with the 95 pickup with the 5vz-fe replacement. These plugs must have a gap; They are out of specification upon arrival. If you have a spark gap tool or shim kit, strip it out, set it to .043" and get going. If you don't have such a tool or kit, make sure you order one. You have an excellent performance. They require a 16mm deep head. I installed them after hand tightening to about 13 ft-lbs of torque. Great product and I will continue to order them when my cars need a new kit.
