Vibrant 14610F Mild Steel Exhaust Manifold Flange Honda F20C F22C S2000 1/2 in.

Vehicle Fitment

• 2000-2003 Honda S2000 AP1 (2.0L F20C DOHC VTEC 4-Cyl.)
• 2004-2009 Honda S2000 AP2 (2.2L F22C DOHC VTEC 4-Cyl.)

Fitment Notes

• Fits Honda F20C and F22C 4-cylinder engines. Both AP1 (F20C) and AP2 (F22C) S2000 variants are confirmed fitments.
• Port sizing is optimized for use with Schedule 10 or Schedule 40 pipe - not standard wall round tubing. See stainless variant 1460F for standard wall round tubing port sizing.
• Sold individually. One flange per purchase.
• When mating to 304 stainless steel tubing, 309L welding filler rod is recommended.
• Stainless steel equivalent (3/8 in. thick, standard wall round tubing): part number 1460F.

Features

• Precision laser cut HRPO (Hot Rolled Pickled and Oiled) mild steel for consistent port accuracy and weldability
• 1/2 in. (0.500 in.) thick construction provides added rigidity over the 3/8 in. stainless variant
• Port sizing matched to Honda F20C/F22C cylinder head outlet geometry and optimized for Schedule 10 or 40 pipe
• HRPO surface finish arrives clean and weld-ready with minimal prep required
• Machined mating surface ensures a tight, leak-free seal against the cylinder head
• Suitable for naturally aspirated and forced induction header and turbo manifold builds on the S2000 platform
• Cost-effective mild steel alternative to the stainless 1460F for Schedule pipe applications
• Backed by Vibrant's 1-year limited warranty

Product Description

The Vibrant 14610F is a precision laser-cut HRPO mild steel exhaust manifold flange designed for the Honda F20C and F22C four-cylinder VTEC engines found in the S2000 AP1 (2000-2003) and AP2 (2004-2009). At 1/2 in. thick, it provides added rigidity over the 3/8 in. stainless variant, making it a popular choice for turbo manifold builds where the thicker flange better resists warping at the cylinder head sealing surface under high thermal loads. Port sizing is optimized for Schedule 10 or Schedule 40 pipe - the thicker-wall pipe commonly used in performance header and turbo manifold fabrication.

The HRPO surface finish requires minimal prep before welding and accepts MIG or TIG with standard mild steel consumables. When joining to stainless steel tubing, Vibrant recommends 309L filler rod for a corrosion-resistant weld joint. Builders using standard wall round tubing should select the stainless steel variant (part number 1460F). Sold individually.
