NGK Iridium IX Spark Plug LTR5IX-11 (Stock No. 4344)
The NGK LTR5IX-11 is a fine-wire iridium spark plug designed for strong ignition and stable idle. It improves cold starts and throttle response, and resists fouling in everyday driving. The iridium centre electrode needs less voltage to fire, which helps under high load or with light tuning.
Use this plug where the vehicle specifies NGK LTR5 heat range with a 1.1 mm factory gap. For exact fitment, use our vehicle lookup or check the Vehicle Fitment tab.
Key benefits
- Fine-wire iridium tip for reliable spark and long life
- Projected tip for efficient combustion and smooth idle
- Resistor type to reduce electrical noise for the ECU and audio

For emissions components this encompasses noise, emissions and balanced back pressure, which have a strong influence on maintaining engine performance (power), and fuel efficiency. Type approval ensures that an aftermarket component will reach, or exceed the performance standard of the corresponding OE part.
Type-approval then, is a certain guarantee that an end user will receive a product of OE equivalent performance attributes.
Products on the Progressive Parts website that meet this approval will be clearly marked or labelled EC or ECE approved.
