We at Diesel Customs LLC strive to be number one in Customer Satisfaction. We hand make every single coil, while wearing nitrile gloves to keep debris off your coils. To top it off, we run every coil through a heated ultrasonic cleaner to guarantee the product you're getting from Diesel Customs, is as clean as possible. No chemicals are used during our ultrasonic cleaning process. We also use organic cotton (Cotton Bacon V2) in our packaging. Packaging that serves a purpose, and is useful. If you're ever left unsatisfied with a Diesel Customs product, or a product from one of our vendors, please don't hesitate to contact us!
