SBP 1999-2003 Honda S2000 AP1 Aluminum Coolant Overflow Oil Catch Can Combo Tank

At Straightboost® Performance, we’re committed to creating innovative solutions for the automotive performance community. We’re proud to introduce our custom-engineered coolant overflow and oil catch can combo designed specifically for the 1999–2003 Honda S2000 AP1.

Why You Need This:

The F20C engine in the S2000 is notorious for oil blow-by. The factory PCV system recirculates blow-by gases, which leads to oil residue and sludge buildup in the intake manifold—robbing performance over time. Our solution? A fully baffled, vented oil catch can system that captures oil and vapor.

Oil Catch Can Features:

• Multi-level internal baffling to separate oil from blow-by gases

• Dual -10AN Fittings for valve cover connections

• Low-profile breather with aluminum retaining plate (no bulky filters)

• 6AN ORB drain port with billet aluminum drain valve, featuring a 1/8″ NPT internal thread to aid oil drainage

• Built-in dipstick for quick level checks

• Vented design: Clean, unrestricted airflow exits through the top-mounted filter

Coolant Overflow Tank Features:

• 0.75-liter capacity

• ¼” barb fitting for radiator hose

• Black billet aluminum vented cap

Build Quality:

• High-grade aluminum construction

• Professionally TIG welded

• Made in the USA

• Made to order – current lead time: 5–10 business days

• Note: Installation requires cruise control relocation or removal

This combo tank is the perfect blend of function, form, and performance—designed with track use, street performance, and engine longevity in mind.
