K&N Replacement Air Filter FORD F150 LIGHTNING 5.4L 1999-2004, F150 Harley-Davidson 5.4L 2002-2003
Description

K&N High-Flow Air Filter | Ford F150 Lightning (99-04) & Harley-Davidson (02-03)

Boost horsepower and acceleration in your Ford F150 Lightning or Harley-Davidson 5.4L with a K&N washable air filter. Lifetime engine protection and easy drop-in install.

The K&N 33-2140-1 is the ultimate performance upgrade for the legendary supercharged 5.4L V8 engines found in the Ford F-150 SVT Lightning and Harley-Davidson editions. Unlike restrictive disposable paper filters, K&N’s "Original High-Flow Air Filter" utilizes four layers of premium oiled cotton gauze. This state-of-the-art design creates an intricate mesh that captures 97-99% of harmful contaminants while significantly reducing airflow restriction.

Engineered to fit directly into your factory air box, this drop-in replacement provides a cost-effective way to improve engine efficiency, throttle response, and overall power. Because it is washable and reusable, it is likely the last air filter your truck will ever need—backed by K&N’s famous 10-Year/Million Mile Limited Warranty.

Best Uses

  1. Performance Enthusiasts: Ideal for owners looking to maximize the supercharged output of the SVT Lightning.
  2. Daily Driving: Perfect for improving fuel efficiency and engine longevity in highway and city conditions.
  3. Eco-Conscious Owners: Reduces environmental waste by replacing dozens of disposable paper filters over the vehicle's lifespan.

Features

  1. High-Flow Media: Advanced 4-layer oiled cotton gauze designed to increase horsepower and torque.
  2. Precision Fit: Specifically engineered for the factory air box of 1999–2004 5.4L F-150 performance models.
  3. Low Maintenance: Can go up to 50,000 miles (or 5 years under normal highway conditions) before requiring its first cleaning.
  4. Tacking Agent Treatment: Treated with a specialized oil that helps the cotton fibers trap microscopic dust and debris.
  5. Washable & Reusable: Designed to be cleaned and re-oiled using a K&N Recharger kit, maintaining "like-new" performance for years.

Benefits

  1. Guaranteed Power Gains: Feel an immediate improvement in throttle response and acceleration.
  2. Long-Term Savings: Saves up to $125 over 200,000 miles by eliminating the need to buy disposable filters.
  3. Engine Protection: Provides exceptional filtration (97%-99% efficiency) to safeguard internal engine components.
  4. Hassle-Free Installation: No tools or modifications required; simply "drop-in" to the existing air intake box in minutes.
  5. Lifetime Reliability: Backed by a Million-Mile Limited Warranty, ensuring your investment is protected for the life of the vehicle.
