Frequently Asked Questions

Will this Banks Power air intake fit my 2007-2008 Chevrolet Avalanche LS?
That application is listed, but confirm the exact engine, emissions configuration, transmission where relevant, production split, and every Banks application note before ordering.

Should I choose a dry or oiled filter?
Choose the filter configuration shown in the title. Dry media is convenient for routine service, while oiled media requires the correct cleaning and reoiling procedure. Do not substitute media without confirming compatibility.

Will this intake require tuning?
Use the Banks application guidance for this exact part. Most intake-only installations do not require custom tuning, but other modifications, emissions rules, and the specific vehicle may change the requirement.
