Frequently Asked Questions
How do I confirm JLT 20-3103-01 matches my intake component?
Match every stated filter or component dimension, flange size, mounting interface, media type, and companion part number. Similar dimensions alone do not confirm compatibility.
Does this pre-filters require an ECU tune?
Tuning requirements vary by exact JLT part number and vehicle application. Follow the current product instructions and do not assume a tune is optional when the listing identifies one as required.
How should the intake system be checked after installation?
Confirm every clamp, coupler, sensor, vacuum line, breather connection, heat shield, and filter is secure. Check for leaks or contact before operating the vehicle under load.
Installation Instructions
Use the current JLT instructions for part number 20-3103-01. Disconnect the battery when required, transfer sensors and lines exactly as directed, secure every coupler and clamp, verify filter and hood clearance, check for intake leaks, and complete any required tuning before full-load operation.
