About Us

SPLUGS is an online business-to-business site targeting industrial spark plug users.  If your engine is spark ignited and fueled by natural gas (NG), compressed natural gas (CNG), or liquified natural gas (LNG), we have a great spark plug for it.

Quality Matters
SPLUGS supplies the highest quality spark plug brands - Caterpillar, Champion, Bosch, and Denso.  Each of these bands has a long history of providing reliable service in Arrow, Caterpillar, Cummins, Deere, Waukesha, Superior, and Wartsila engines.
We Understand
You may be responsible for a 24/7 operation and have a budget to meet.  We'll supply the spark plugs at a price that will help with that budget and keep the equipment operating.  We understand because we've been part of gaseous-fueled engine operations for 30 years.
