Original Equipment Replacement Wires / Complete Ignition Wire Set - 5mm

Product Features:
  • Original Equipment Replacement Wires / Complete Ignition Wire Set - 5mm
  • DENSO First Time Fit ignition wire sets are identical in form, fit, color, and performance to the factory-installed wire sets
  • Every part the wire set's construction meets or exceeds OE/OES specifications
  • Each wire is pre-cut to exact length so the wire set is ready to install right out of the box
  • Identical OE end caps are designed to "click" in place for a secure fit, allowing the installer to "feel and hear" that a solid connection has been made, even when the connection is in a difficult-to-see location
  • Through a patented process, the terminals are attached to provide an extremely strong connection, ensuring the cable and boot will not separate during removal and installation

Comments about Denso Ignition Wire Set:

Denso calls these a direct OE replacement cut to exact length to fit a 1999 Tacoma with a 2.4 engine. This could not be any further from the truth. When I removed the factory original wires I could not help but notice the difference in length. #1 was 2 1/2" longer, #2 was 6 1/2" longer, #3 was 4 1/2" longer and #4 was 1/2" longer. Far from exact replacement. I called Denso to let them know how bad the wires were so the service tech checked the lengths of the wires that make up the set and sure enough they are all too long. He apologized for Denso making such a poor product and added my complaint to other complaints that they have received on this set. If you don't mind wires flopping around because you can't use the factory wire retainers and don't care what your engine bay looks like go ahead and order these. I am too sick and tired of the one size fits all mentality to install them on my truck. NGK Part #4441 is an exact fit but are blue instead of black.
