If you own an early 123 4-cylinder diesel, then this is a must-have diesel engine kit! This glow plug upgrade will do three things that will put a smile on your face: 1. Your engine will start faster and cold idle smoother. 2. Your glow plugs will last longer. 3. If you should burn out one or two glow plugs, your engine (if healthy) will still start!
Product Details
If you have ever been stranded with bad glow plugs before, you know the frustration. This kit will allow you to throw away your old series-style glow plugs and replace them with the more efficient pencil-style parallel glow plugs used in the newer diesels. You will also receive a PDF installation manual that contains step-by-step instructions with photos to help you to do the conversion yourself.
The complete kit includes
- 4 German-made Fast glow plugs (large thread style)
- 3 special wire connectors
- 2-up instructions to download
Please note. You will lose a correct functioning glow light when you install these new plugs. You will have to use a mental count to determine how long you have your key turned to the glow position. Once completed, you will immediately notice an improvement in your start times. Cold starts can be done with only 8 to 12 seconds of glow time, and hot starts with 2 to 3 seconds. You will love this upgrade!
IMPORTANT WARNING: If your factory relay is acting up or not working properly, then this kit will not work. I recommend you purchase our complete kit, which has a manual push-button control. You can opt for the kit shown below that bypasses your factory relay and gives you "push button" manual control.
