Why we choose Ramair
Not every supplier makes the cut. Ramair is on the shelf because four decades of British filtration, from Formula 1 airboxes to the Time Attack grid, go into foam that protects hard-driven engines without choking them.
"We say that each filter is capable of flowing more air, but the rest is up to you." Dan Mullan, Operations Director, Ramair
1
Foam that filters in stages
Every element is made from Aeriform, two foam layers giving variable stage filtration: high airflow up front, fine particles stopped before the engine. It keeps working in damp British conditions that send paper filters soggy, and it carries a lifetime warranty for the original purchaser.

Proven where it's loudest
Since 1981 Ramair has supplied filtration across Formula 1, Formula 3, DTM, WRC, Formula Ford, the Le Mans Series, BTCC and WTCC. Racing is where filter failures get found fast, and that data feeds the road-car range.

Honest engineering, made in-house
CAD design, SuperFlow flow-bench testing, silicone production and hand finishing all happen under one roof in Wiltshire. Every filter is tested against the standard part, and Ramair refuses to invent power figures: more air, and the rest is up to your build.

Before you order
Ramair questions, answered
Foam or paper: which actually filters better?
Ramair's Aeriform foam uses two layers for staged filtration: it holds its airflow as it loads up, where paper elements clog and choke, and it copes far better with damp air. Every element carries a lifetime warranty for the original purchaser.
PRORAM, Jetstream or SR: which kit do I need?
Three families at different budgets: SR Performance foam kits are the value route, Jetstream foam kits add heat shields and large-bore intake pipes, and PRORAM pleated kits sit at the top of the range. Tell us the car and the goal and we'll point you at the right one.
Can you fit and tune my induction kit?
Yes. Have us fit it in our workshop and pair it with our custom ECU tuning so the intake and the map are set up together, or we'll ship it with Ramair's full photographic instructions if you'd rather do the spanner work yourself.
What are lead times on order-in items?
Plenty of Ramair lines are on the shelf, and order-in parts come quickly from Ramair's Wiltshire facility, which despatches stocked lines next working day. We'll give you a real date before you commit, not after.
