NEUSPEED HI-FLO Air Intake Kit | N18 • R-ChassisDESCRIPTION The 'Open Air Box' system gives you the abundance and unrestricted 360 of air source compared to OEM's sealed airbox with a flat filter and tube fed air source. During R&D, we installed temperature probes around the engine compartment and the gauge showed the inside temperature matched the ambient after vehicle speed past 20 mph.

Quality part at reasonable price.
Had the exact same appearance as the Motorcraft kit. Installed the same and so far no issues at all. Cost on this was less than half of the Motorcraft kit.
