⚡ At a Glance
- • Idle Control: Varies the cross-sectional area of the idle air passage according to engine temperature and load
- • Best for: Owners of Porsche 996 (1999-2001) and 986 Boxster (1997-2004) needing a direct replacement idle valve
- • Not ideal for: Vehicles outside the listed compatibility reference or users who require manufacturer-confirmed alternatives
An adjustable valve modulates airflow through the idle passage to keep idle speed stable under different conditions. Direct replacement part numbers match original standards for a straightforward fit.
Steadier idle and fewer surges - with adjustable idle air passage control
An internal valve varies the cross-sectional area of the idle air passage in response to engine temperature and load, modulating airflow to maintain idle speed. The mechanism alters airflow rather than changing fuel delivery, focusing on idle stability.
Reduced rough idling and fewer stalls help engines settle at a consistent idle, improving drivability during warm-up and low-speed manoeuvres.
Simple fitment for quicker repairs - with OEM-aligned part numbers
Part numbers listed include 0280140572 and 99660616001, matching original standards for direct replacement. The design requires no drilling or cutting during installation.
A straightforward swap shortens workshop time and allows owners or technicians to replace the valve without modification to surrounding components.
Longer service life under normal use - with premium construction materials
Manufactured from high-quality materials intended to withstand operating stresses and repeated thermal cycles. Construction aims to meet original fit and durability expectations.
Fewer early failures and reduced need for repeat replacements give greater confidence after fitting, especially on higher-mileage engines.
