Product details

CONDITION OF THIS SPECIFIC OFFER: Damaged in transit. Bracket is scratched. The K&N Air Oil Separator protects the engine and intake tract from blowby by capturing the oil in our industry leading high capacity reservoir. This helps prevent power loss and possible engine damage caused by blowby. The K&N Air Oil Separator is quick and easy to install in about 30 minutes with basic tools and uses factory-style hose connections to quickly snap on and off. The oil separator replaces the factory line from the crank case allowing the oil separator to be mounted to a coinvent location in your engine bay. No tools are needed to check and empty the oil collector reservoir. Each unit is engineered specifically for your vehicle and is backed by our No-Hassle Lifetime Limited Warranty. The K&N Air Oil Separator protects the engine and intake tract from blowby by capturing the oil in our industry leading high capacity reservoir. Oil Catch Can

BEFORE YOU ORDER

A few things to know.

How do I order these parts?

Add your exact parts and delivery details, then continue to payment. Eligible orders show the final parts, shipping and tax total and a PayPal button here after automatic checks. Freight, oversized, custom and uncertain items go to JuiceBuilt for a quote. You are charged only after approving PayPal; supplier orders are submitted separately after verified payment.

Does a part number guarantee vehicle fitment?

No. Product descriptions are supplied by the manufacturer. Check the manufacturer application information for your exact vehicle, engine and supporting modifications. Online checkout requires your exact-part fitment acknowledgment. Contact JuiceBuilt before ordering if you need fitment help.

Is the stock shown reserved for me?

No. Availability is a dated supplier snapshot. Inventory can change, and adding a part to your build does not reserve it. Availability and delivery are checked again before payment. A supplier order is confirmed separately after payment.

What about shipping?

Eligible standard-size parts orders with a parts subtotal of $100 or more receive free standard shipping. The minimum applies after coupons and other discounts.

The same $100 minimum applies to all brands, including Aerospace Components.

Oversized and freight items are excluded from free shipping at every subtotal, including carbon doors, hoods, trunks and similar large panels. Their shipping charge is quoted separately before payment.

Shipping for orders below $100 is calculated before payment.

Online checkout is initially available for US delivery addresses. For other countries, contact JuiceBuilt for a manual quote before payment.
