Product Details

The DENSO 5401 Iridium Power spark plug delivers superior ignition performance through advanced materials engineering. Featuring the world's smallest center electrode at just 0.4mm diameter, this plug utilizes iridium's exceptional durability and heat resistance to create a more focused spark for improved combustion efficiency.

Key Features:

  • Ultra-fine 0.4mm iridium center electrode for enhanced ignitability
  • Improved throttle response and acceleration
  • Better fuel efficiency through optimized combustion
  • Longer service life compared to conventional platinum or copper plugs
  • Reduced voltage requirements for reliable cold starting
  • OE-quality construction from a leading original equipment manufacturer

DENSO's Iridium Power technology concentrates the electrical energy into a smaller, more powerful spark, ensuring complete fuel burn and reduced emissions. The iridium alloy tip can withstand extreme temperatures up to 4,000°F while maintaining electrode shape over extended service intervals.

fast very good price and easy to work with web page

Easy to use website thanks

This muffler assy. fit my basic 1988 Toyota truck with 103 inch wheel base perfectly. Installed very easily and worked quite well. Installation note: after removal of the old assy. remove the two muffler rubber suspension hangers that are above and near the axle. Install them on the muffler hangers first, then install the assy. Will make the installation much easier.

Easy website site to navigate

good service

Product was delivered and item was as discribed. However it did take a little longer to ship than what is the new normal. (3 business days ) shipping address to delivery address is 3 hours by car. Over all experience with this company was good.
