HO20-185 - NATURAL MID MOUNT LS ACCESSORY

Includes SD7 A/C Compressor, Alternator, P/S Pump, Tensioner, Belt, Crank Damper & Pulleys

Part Number: HO20-185

Holley's Mid-Mount complete accessory system has all accessories pulled in tighter than other accessory drives. At the heart of the system is a "bracketless" design, where the accessories bolt directly to the water pump for a clean, integrated form. The design offers superb engine visibility to show off your horsepower, not your accessories. Among the many swap friendly features are bottom heater outlets for clearance in tight applications. The Holley designed alternator is just as innovative. This premium alternator utilizes 6-phase technology as found on the C7 Corvette. The water pump also shares its design efficiencies with that of the C7 Corvette. The compact and reliable SD7 A/C compressor and Type II P/S pump with baffled reservoir are also integrated. The Mid-Mount drive completes Holley's trilogy of accessory solutions giving a third option compared to the High and Low-Mount previously released. All three accessory solutions are for LS engines.
When we say "complete", we mean complete. The Mid-Mount system comes with everything you need. All accessories are included; the water pump, A/C compressor, Alternator, P/S pump with reservoir, and the crank damper. All pulleys and the belt are supplied. Even heater hose adapters, power steering to -6 AN hardline, and the alternator plug/harness are included. Easy assembly was a priority during the entire development of this accessory solution. Color graphical instructions walk you through every step of the ultra-easy installation.

These things are awesome. I'd say they are on par with what comes on the car from factory.

Perfect fit for my 2018 Civic—easy, affordable, and worth it
Size: 9.5" x 10.9" x 2.1"
I’ve bought this cabin air filter multiple times for my 2018 Honda Civic, and it’s consistently great quality. It fits perfectly and is super easy to install—takes just a few minutes to swap out, and I always do it myself. Way cheaper than going to a shop or dealership. The airflow is smooth, there’s no smell at all, and it keeps the inside of my car feeling clean and fresh. No weird odors, no dust blowing in—just a solid, dependable filter that does its job well. This is the only one I’ll keep buying.
