We have just released a new catalogue of coil-on-plug boots. The new catalogue contains 160 types of coil-on-plug boots for more than 4000 car models. TESLA was once the first company to introduce this range to customers in Europe. With the publication of the new catalogue, we have further strengthened our current position as the largest supplier of this range on the European market.

The catalogue contains an alphabetical list of car models and the corresponding types of coil-on-plug boots. In the second part of the catalogue, the boots are traditionally sorted by their numbers. For each type there are images, basic technical data, and an overview of all models. The last part of the catalogue contains many OE numbers to make it as easy as possible to find the right type of the coil-on-plug boots.  At the end of the catalogue, we have written a small recommendation on how to properly care for the ignition system and how to extend its life in a very simple way.

The new catalogue is available for download on our website under Coil-on-plug boots.

Every car owner tries to do only the best for his car. Ideally, if it is almost free, it can improve the functioning of the engine and at the same time extend the life of its important parts.

However, one option that is far from being used by everyone is the correct application of dielectric silicone grease.

We supply the grease free of charge as part of packages of ignition coils and coil-on-plug boots. This is a 0.5 g pack. The pack can also be purchased separately. In addition to this small pack, we also offer a 10 g pack in a tube, which will be especially appreciated by service and specialist shop owners. 

What are the main advantages of using dielectric grease?

- As a great insulator, grease improves insulation and helps prevent voltage leaks in the ignition system. This can significantly extend the life of ignition parts. This effect is achieved because the grease prevents arcing (unwanted electrical discharge).

- The grease significantly reduces the risk of the spark plug sticking to other ignition parts.

- The grease contains silicone, making it hydrophobic (waterproof). This helps repel moisture, preventing corrosion that could significantly degrade the quality of the electrical connection.

- The dielectric grease prevents dirt, water and contaminants from reaching the spark plug.

- The grease is an insulator that resists extreme temperatures, preventing thermal damage to parts.

- Silicone grease is a low-maintenance product that can remain effective for a long time.

How to apply silicone grease correctly?

Due to its non-conductive nature, dielectric grease must NOT be applied to metal contacts of ignition parts. Follow the instructions below when applying the grease:

1.            Remove the spark plug.

2.            Clean the spark plug and silicone boot with a cleaner and with a wire brush.

3.            Squeeze a small amount of silicone grease onto a cotton swab or brush.

4.            Use the swab or brush to apply a thin layer to the inside of the boot.

5.            Always ensure that the grease does not get on the metal contacts of the ignition parts.

The use of silicone dielectric grease offers several advantages. To achieve these benefits, it is essential to follow the basic above-mentioned guidelines for proper application. If you need help, please contact us at any time. We will be happy to advise you.

As of 01.08.2023, we are expanding our range of coil-on-plug boots and including new types. You can find all new boots in the search engine on our website and in the TECDOC database. For each type, we have traditionally attached a photo and product information including technical data as well as data on the models and car makes for which these boots are intended.

In addition to the new coil-on-plug boots, we have also thought about optimising packaging, transport, and associated costs. We have added new boxes to our range that are primarily designed for the smallest types and their accessories such as guide rings and springs.

A new catalogue of all our coil-on-plug boots will be published by the end of September 2023. The catalogue will be available for download on our website. 

Even before this expansion, TESLA BLATNÁ was already the largest supplier of coil-on-plug boots in Europe. With the addition of more than 40 new types, we have further strengthened this leading position.
