Both the AP1 and AP2 Honda S2000 oil pans are compatible with the Moroso Drop and Weld in trap door baffle system. Three trap doors and two anti-slosh plates feed the baffle assembly, which provides an oil containment area. Heavy-gauge aluminum construction with aluminum trap doors. The baffle assembly is installed by inserting the self-positioning component into a clean, grease-free OEM S2000 oil pan and having it stitch welded in by a skilled aluminum welder.
