Harley Davidson M8 Touring Stealth Air Cleaner Kit

By   on  Verified Purchaser

Review is for kit p/n 170-0354C, Harley Davidson 2017-2021 M8 Touring. Nice kit, easy install. I ended up using the Slasher teardrop cover for the classic look. Parts Giant delivered fast and provided great service. There was a minor issue with my order that was taken care of easily and quickly.


Thank you

I love it.


Great product

By   on  Verified Purchaser

Great product and value, I'll be getting another one for the wife's bike. Requires a tune from the harley shop or a tuner you purchase and install yourself. Easy 20 minute install and fit behind the stock air cover.


Extremely happy

Questions & Answers

will it fit on my 1997 883 sportster

Yes, there is a kit offered to work on that 1997 XL883. Just be sure to select that bike when you add the kit to your cart.

Answer Question

I currently have a s&s carb with a teardrop cleaner and the cover just my calf and I cannot ride will with kit replace the teardrop?

Yes, this air cleaner will replace the teardrop cover on your bike's current air intake setup. Depending on your size, however, it may not fix the proper entirely. Your best bet would be to remove the teardrop portion of the air cleaner that's on your bike right now, but leave the filter element in place. That'll give you a pretty good idea as to whether or not this aftermarket air cleaner intake from S&S will help with your comfort needs.

Answer Question

Does fitment matter if my 2005 XL883L is carbed and not EFI?

So long as your have the original carburetor on your machine, you won't have any problems fitting the Stealth air cleaner to your bike. It's designed to bolt right onto the OEM XL883L carburetor with ease.

Answer Question

Can you put the stock Harley cover over it?

Yes, you absolutely can. S&S' Stealth Air Cleaners are designed to work well with the OEM air cleaner cover, or a variety of S&S air cleaner covers.

Answer Question

how to clean filter

To clean the S&S Stealth Air Cleaner filter, we recommend using a K&N Air Filter ReCharger Kit. With that, you'll have everything you need to fully service the S&S air filter.
