K&N Gasoline Fuel Filter PF-1100 for 1983–2004 Nissan/Infiniti — High-Efficiency Pleated Media, Low-Restriction Flow

Built for drivers who expect dependable fuel delivery and long-lasting protection, the K&N PF-1100 fuel filter fits many 1983–2004 Nissan and Infiniti fuel-injected gasoline engines. Its pleated, high-efficiency media and heavy-duty steel canister are engineered to remove debris that can foul injectors, intake ports, and carburetor jets without creating restrictive flow. This filter is a direct replacement for many OEM parts and is sized to provide large contaminant capacity and durable, corrosion-resistant performance.

How does this filter keep fuel systems cleaner?

The PF-1100 uses multi-layer pleated filtration media to capture particles and contaminants before they reach injectors or intake components. By stopping grit and sediment, it reduces the risk of deposit buildup that can affect spray patterns and engine responsiveness.

• Pleated high-efficiency media for fine particle capture
• Large internal capacity to hold more debris between changes
• Reduces wear on injectors and intake components

Will using this K&N filter affect fuel flow or engine performance?

Designed for low restriction, the PF-1100 balances filtration with high flow to maintain reliable fuel delivery under normal and demanding conditions. That means your engine gets clean fuel without the pressure drop that can reduce throttle response.

• Engineered to preserve stock fuel pressure and flow
• Low-restriction design suitable for stock and lightly modified engines
• Heavy-gauge canister construction resists deformation under line pressure

Is this a direct replacement for my Nissan or Infiniti model?

The PF-1100 is manufactured to meet or exceed common OEM specifications, making it a straightforward swap for compatible 1983–2004 Nissan and Infiniti gasoline fuel-injected engines. Always cross-check part numbers and vehicle fitment before purchase to confirm compatibility.

• Direct-replacement sizing and fittings for compatible models
• Meets or exceeds original equipment standards for fit and function
• Simple install using standard fuel-line connections

How long will this fuel filter last and what maintenance does it need?

Longevity depends on fuel quality and driving conditions, but the PF-1100’s large capacity and robust media deliver extended service life compared with lower-grade disposable filters. Inspect or replace the filter per your vehicle manufacturer’s recommended intervals or when fuel system servicing indicates reduced flow or contamination.

• Large contaminant capacity for extended service intervals
• Heavy-duty steel canister for corrosion resistance and durability
• Compatible with routine fuel-system inspections and maintenance
