Spark Plug Protector

Protect your plugs with our impact resistant and water resistant plug case. An O ring seal and quick latch mechanism prevents unwanted water or mud intrusion. A TPU soft rubber insert keeps your plugs from rattling around and breaking the ceramic. Recommended to print the inner m12 or m14 plug holder in TPU and the o ring seal in TPU. 2x M3 heat set inserts are recommended for the lid assembly, as well as 2x 3mm SHCSs
