In response to the demand to extend our Phenolic Spacer lineup to include some of the older subaru models, we now have created intake manifold thermal spacers for Impreza/Legacy/Forester 99+ 2.5 N/A and 99+ 2.2 N/A 'Phase 2' engines.Thermal spacers lift the intake manifold off the super heated engine to lessen the transfer of heat. Both the intake manifold and engine block are aluminum so the high heat transfers very quickly, these spacers stop that. The cooler the intake charge the more HP a...
