Please note before ordering the TUNE+

We strongly advise you to check the dimensions of the 123/TUNE+ with the original distributor cap AND to carefully read the installation manual before you order!

Coil and spark plugs

Although used coils all look alike, they should be viewed with suspicion since one cannot tell from the outside whether and how often they were exposed to overheating in the past. Installing the 123ignition system will ensure that the coil will never overheat again in the future. Of course you can also easily order this here, we recommend the 123 Red Coil.

Perhaps you will also need new spark plugs? At 123ignitionshop we have added the spark plugs most commonly used in addition to the 123ignitions we offer. See: the spark plugs list.
