## Overview

The Denso IXUH22I Iridium Power Spark Plug features a groundbreaking 0.4mm iridium center electrode, the smallest in the world, designed to maximize ignition efficiency. Its patented U-groove and taper cut ground electrode promote faster flame growth while minimizing voltage needs. Built with DENSO’s 360-degree laser welding technology, it guarantees exceptional durability and performance, making it a top choice for cars and trucks seeking enhanced throttle response and fuel economy.

## Description

Increased performance with World's smallest Iridium Center Electrode (0.4mm). To increase ignitability, the important point is to let the flame kernel produced by the spark to grow unobstructed. Normally, this can be accomplished by widening the spark gap. However, this causes spark voltage to increase, which has the opposite effect. Iridium Power uses DENSO's patented U-Groove ground electrode to achieve maximum ignitability while minimizing required voltage.

Review: Replaced along with some bad ignition coils - My 2017 Kia Forte was throwing out ignition error codes, so I replaced all the ignition coils and spark plugs. They arrived quickly, seem to be of good quality, and installed as expected. This happened about two years ago, and I have not had any issues since, so I would say that they are performing well.
Review: My Honda Odyssey feels more peppy and responsive with this spark plug - Great Spark Plug. It makes my 120K miles Honda feels like new again.

Great Spark Plug. It makes my 120K miles Honda feels like new again.

### ⭐⭐⭐⭐⭐ Honda Pilot plug
*by G***. on August 11, 2023*

Wife's car has 130k miles. I've never done anything on it but its been very reliable. Decided I need to start doing some PM and this was part. Old plugs didn't look too bad, but these couple with a transmission/PS fluid change and some fuel injector cleaner has the car running like a champ.
