This SLEEVE SPARK PLUG is precision-machined for direct fitment over the spark plug well on the Bajaj Tricab cylinder head, with its inner bore diameter, wall thickness, and seating shoulder profile accurately toleranced to guide the spark plug socket and maintain a sealed passage through the cylinder head casting. Functionally, it protects the spark plug well from oil and coolant intrusion while providing a stable access channel for plug installation and removal, and if the sleeve seal degrades or the bore develops corrosion, it results in oil seepage into the plug well, fouled electrode contact, and inconsistent ignition performance. Supplied in authentic Bajaj sealed packaging with a hologram genuinity verification strip, this sleeve spark plug is manufactured to maintain a secure, contamination-free plug well passage.
