Ramair SR Performance Intake Foam Air Filter Kit – Vauxhall Astra H MK2, Zafira 1.4i, 1.6i & 1.8i
The Ramair SR Performance Intake Kit is a direct replacement for the standard airbox on the Vauxhall Astra H MK2 and Zafira with 1.4i, 1.6i, and 1.8i petrol engines. It is designed to allow the engine to breathe more freely, reducing the restrictions built into the factory air intake system and improving throttle response in the process.
The centrepiece of this kit is Ramair’s twin-layer dry foam filter, constructed using their Aeriform foam with a T304 stainless steel cage for structural support. The same filter construction is used in motorsport applications, which speaks to its build quality. The foam is designed to flow significantly more air than a standard paper filter while still trapping dirt and debris – keeping your engine protected over the long term.
One important detail worth noting: this kit is MAF safe. MAF stands for Mass Air Flow sensor – a component your car uses to measure incoming air and adjust fuelling accordingly. Some induction kits can interfere with MAF readings, but Ramair’s twin-layer foam is specifically designed to avoid this issue, meaning no unwanted side effects from fitting.
Key Features
- Twin-layer dry Aeriform foam filter – no oiling required
- T304 stainless steel cage for rigidity and long-term durability
- MAF safe design – compatible with your car’s air flow sensor
- Replaces the restrictive standard airbox
- Comes with all necessary fitting hardware included
- Easy to clean with warm soapy water and reuse
- 100% handmade in the UK, with a lifetime guarantee against manufacturing defects
What to Expect
Fitting this kit in place of the standard airbox should deliver a more immediate throttle response and a noticeably improved induction sound under acceleration – something many drivers find genuinely satisfying. Outright power gains on naturally aspirated engines like these are typically modest rather than dramatic, but the improvement in engine response and the long-term cost saving of a reusable, cleanable filter make this a worthwhile upgrade for any enthusiast.
