The K&N KN-170C is a premium Chrome spin-on oil filter specifically designed for Harley-Davidson motorcycles. It is the chrome equivalent to the black KN-170B.

While it looks very similar to the KN-171C we discussed earlier, the KN-170 series is a shorter "compact" filter, typically used on older Harley models or where clearance is extremely tight.

Key Specifications

  • Finish: Triple-plate Chrome (high-luster).

  • Height: 2.97 inches (75 mm) — This is significantly shorter than the KN-171C (3.70 in).

  • Thread: 3/4 In. - 16 UNF.

  • Removal Nut: 17mm welded hex nut (pre-drilled for safety wire).

  • Bypass Valve: Yes.

Primary Fitment: The "Evolution" & "Early Twin Cam" Specialist

The KN-170C is the go-to for riders who need a shorter filter body to clear frame rails or exhaust pipes. It primarily fits:

  • Harley-Davidson Evolution (Evo) Engines: Late 80s and 90s Softails and Sportsters.

  • Early Twin Cam 88 Engines: Many 1999–2006 models.

  • Sportster Models: (1984–2022) - Many riders prefer the shorter 170 over the 171 for a "tucked in" look.

  • Custom Builds: Ideal for "Chopper" frames where the oil filter mount is positioned close to the front down-tubes.

KN-170C vs. KN-171C: Which one do you need?

Feature KN-170C (Short) KN-171C (Standard)
Height ~3.0 inches ~3.7 inches
Filtration Surface Slightly less Slightly more
Clearance Best for tight spots Standard fit
Interchangeable? Often yes (threads match) Often yes (threads match)

Tech Note: Because the KN-170C has a smaller internal volume, it holds slightly less oil. If your bike can physically fit the taller KN-171C, many mechanics recommend it for the extra filtration surface area. However, if your exhaust is in the way, the KN-170C is your best friend.

Why the Chrome Finish?

The "C" designation means this filter is meant to be seen. On most Harleys, the oil filter is front-and-center. The KN-171C provides:

  1. Corrosion Resistance: The chrome plating helps protect the canister from road salt and moisture.

  2. Easy Cleaning: Road grime wipes off chrome more easily than matte black paint.

  3. The Nut: Having a 17mm nut on a chrome filter is a lifesaver; you won't ruin the finish with a "claw" or "strap" style wrench.
