These precision machined stainless plugs will safely and accurately seal the glow plug passages in your cylinder heads. These delete are very popular among high performance engine builds, as well as those living in warm climates.
This kit serves as an excellent improvement for L5P customers having repeatable premature glow plug failures. In some extreme cases we've actually seen glow plug tips fracture and fall into the cylinder causing internal damage.
One kit includes eight glow plug deletes so only one part number per truck is needed.
