Sinister Diesel Pre-Filter Sock for Cold Air Intake
Description
The Sinister Diesel Pre-Filter Sock is a durable protective cover designed to fit over your cold air intake filter, helping block larger debris like dust, dirt, and bugs before they reach the main filter element. Built from rugged, breathable material, this pre-filter helps extend the life of your intake filter and maintain airflow in dusty or off-road conditions.
Easy to install and remove for cleaning, the pre-filter sock is an affordable upgrade for trucks and diesel applications where additional protection from road particles and harsh environments is needed. Keep your cold air intake cleaner and running longer with this simple yet effective accessory.

How it works
After checkout, we route your vehicle info and part SKU to verified installation shops near you. Local installers review the job and submit competitive bids; you pick the shop you want based on price, reviews, and availability. Your name and email stay private until you select an installer.
Pricing
You pay for the bid from your preferred shop. The full amount is shown before you confirm — installers cannot add charges without your written consent. Payments are processed securely by Stripe.
Your privacy
During bidding, shops see only your service ZIP code, vehicle year/make/model, and the part SKU — not your name, email, or address. Only the shop you select receives your contact details after payment. We never sell your personal information.

About Sinister Diesel
Sinister stands for everything diesel and they have made a name for themselves manufacturing some of the highest quality diesel engine components in the industry. The Sinister Diesel brand was born out of an idea from the founders while working on one of their own trucks. What if they started their own diesel performance business manufacturing and selling high quality air intake, fuel, and engine components? That idea transpired into the Sinisterl Diesel we know today. In order to make sure that when you popped the hood, you could easily distinguish a œSinister branded part from other companies, nearly everything they manufacture is coated in their trademarked œSinister Blue. Whether you drive a Cummins, Powerstroke, or Duramax, they can outfit your entire truck with cold air intakes, fuel tank sumps, oil filtration, regulated fuel return kits, and so much more. If you're looking for quality performance parts at a great price, look no further than Sinister!
