Curated Selection｜其他商品｜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.
