Cleaner Oil, Longer Engine Life: Hot Shot’s Secret Launches Pure Diamond Bypass Filtration System

Hot Shot’s Secret has expanded its lineup of engine maintenance products with the introduction of the new Pure Diamond Bypass Filtration System, a supplemental oil filtration system designed to keep engine oil cleaner for longer while helping extend engine life across a wide variety of applications.

Unlike a traditional full-flow oil filter, the Pure Diamond system continuously filters a small portion of the engine’s oil through densely packed depth-media filtration. This allows it to capture contaminants that conventional filters often miss, including wear metals, carbon soot, and dirt. According to Hot Shot’s Secret, the system filters particles as small as 2 microns and removes up to 96 percent of wear-causing particles in the critical 2-to-5-micron range—debris that can continue circulating through an engine with a standard OEM full-flow filter.

A Modern Take On A Proven Design

The Pure Diamond system builds on a filtration concept that has been trusted for decades, but Hot Shot’s Secret has modernized the package with updated hardware and vehicle-specific installation options.

“Pure Diamond represents the evolution of a time-tested filtration concept,” said Hot Shot’s Secret Brand Manager Josh Steinmetz. “We’ve taken a proven Frantz Filter bypass design and updated it with modern stainless steel braided hoses, optional sampling valve, and application-specific kits, giving customers a practical way to keep oil cleaner and help support long-term engine durability.”

Because bypass filtration operates independently from the factory oil filter, it can focus on filtration efficiency rather than maximizing oil flow. Oil is diverted through the Pure Diamond filter at a carefully controlled rate before returning to the engine, allowing for much finer filtration without affecting normal oil pressure or lubrication.

Part Of A Complete Maintenance Strategy

Hot Shot’s Secret positions the Pure Diamond system as more than just an accessory. The company recommends pairing it with routine oil analysis, its TBN Booster additive, and Blue Diamond PAO-based engine oils to create a comprehensive oil management program. The goal is to maintain cleaner oil, support consistent lubricant performance, extend service intervals, and ultimately reduce maintenance costs over the long haul.

The Pure Diamond Bypass Filtration System is available in application-specific kits for numerous engine platforms, including popular diesel pickups, along with universal mounting options for custom installations. Replacement filter elements are designed to be inexpensive and easy to service, making the system practical for long-term ownership.

The Pure Diamond Bypass Filtration System is available now through authorized Hot Shot’s Secret dealers and directly from HotShotSecret.com. The company is also offering installation videos, technical resources, and product information to support both do-it-yourself enthusiasts and professional installers.
