Jackal Motorsports Intake Spacer Kit – Audi B6/B7 S4 & C5 4.2L 40V V8

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.

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.
