Upgrade your Audi B6/B7 S4 or C5 4.2L 40V V8 with the Jackal Motorsports Intake Spacer Kit, designed to combat engine heat soak and improve performance.

Our precision-spacers isolate the intake manifold from the cylinder heads, reducing heat transfer and lowering intake air temperatures for a denser, cooler charge. The result: smoother airflow, more consistent power, and a cooler-to-the-touch manifold — especially noticeable on ported intake setups.

Built from high-temperature, oil-resistant material, these spacers are engineered for long-term durability under demanding conditions.

Features

• Fits Audi B6/B7 S4 4.2L 40V V8 and C5 4.2L 40V V8
• Available in 10mm, with 12mm and 14mm options coming soon (dyno data pending)
• Includes:
• (2) Spacers (Driver and Passenger specific)
• Integrated O-ring grooves for a perfect seal (O-rings included)
• (14) extended allen-head bolts for proper manifold mounting
• Reduces intake manifold heat soak
• Promotes smoother airflow into the cylinder heads
• Simple bolt-on install — torque to factory specs

Why You Need This

Audi’s 40-valve V8 engines are known for heat soak, where cylinder head heat transfers into the aluminum intake manifold, robbing power and consistency. The Jackal Motorsports spacers break that thermal bridge — improving intake temperature stability and performance across repeated pulls or track sessions.

Proven design. Real results. Cooler charge temps, better flow, and more consistent power.
