K&N's 54 Series shielded air intake system is a universal cold air intake system. The 54 Series assembly is designed to increase volumetric efficiency and engine horsepower. The intake incorporates a K&N famous cotton gauze air filter which is removable for periodic cleaning and provides the benefit of an open cone filter and standard air box in one unit. The plastic injection-molded housing acts as a heat shield to prevent any power loss. Assembly designs were flow tested for many hours before our engineers completed the shape to provide high flow with low restriction and great filtration all in a small space. Included in the box is a template to cut your own vinyl wrap for personal customization of the housing. The assembly comes with a 76mm air filter base flange and a 100mm housing intake diameter. The filter base incorporates a 1/4 inch NPT threaded fitting to attach an optional vent adapter.

Fitment

  • Will this fit my truck?

    The Fits section at the top of the page lists the manufacturer's applications for this exact part. If your year, make and model is not there, or you are not sure, text us a photo of what you are replacing with your year and engine and we will confirm it before you order.

  • What if I order the wrong part?

    Call or text us before it ships and we will swap it. After delivery you have 30 days to return it in new, uninstalled condition. The return policy has the restocking details.

Shipping

  • When will it ship?

    In-stock parts usually ship within 1 to 2 business days from warehouses across the USA. The stock line under the options tells you the status of the part you are looking at. Large items ship LTL freight and we call to schedule delivery.

  • Why did I only get part of my order?

    We ship from multiple warehouses, so an order with several items can arrive in more than one box. Tracking for each shipment is emailed as it goes out. Full details in the shipping policy.

Returns and warranty

  • What is the return policy?

    30 days from delivery, in new and uninstalled condition, with a restocking fee. Everything is spelled out in the Returns & Refund Policy.

  • How do warranty claims work?

    We are an authorized dealer, so the manufacturer's warranty applies to every part we sell. Call or text us with your order number and we handle the claim with the brand for you.

Paying

  • Can I pay over time?

    Yes. Shop Pay installments are offered at checkout on qualifying orders, and the monthly estimate shows right under the price.

  • What is a core deposit?

    Some remanufactured parts, like injectors and turbos, carry a refundable core deposit. It is shown on the product page when it applies and refunded when your old part comes back to us.
