Keep spark energy traveling cleanly from the coil-on-plug (COP) coils to the spark plugs with the DENSO Auto Parts Direct Ignition Coil Boot Kit 671-6315 (also written 6716315), a cost-effective tune-up piece for modern engines. This six-boot set (COP Boots-6) drops in for the 2004-2006 Toyota Camry, 2004-2010 Toyota Highlander, 2004-2006 Toyota Sienna, 2004-2008 Toyota Solara, 2004-2006 Lexus ES330, 2004-2006 Lexus RX330, and 2006-2008 Lexus RX400h — see the Buyer's Guide tab for engine-level applications.

The ignition coil boot bridges the coil and the spark plug, insulating the high-voltage connection and sealing the plug well. Cracked, hardened, or oil-soaked boots can allow spark leakage, misfire, and rough running; if worn boots are the cause, this kit replaces them.

  • OE/OES design: insulator and spring built to match factory geometry for a precise, first-time fit.
  • DENSO First Time Fit: identical in form, fit, color, and performance to the factory-installed boots.
  • Tested to OE/OES standards for reliable, repeatable performance.
  • Complete set of six boots — a practical tune-up solution for high-mileage engines.
