Frequently asked questions

The main difference between our Ramair foam filters and pleated filters lies in the filtration media used:

• Ramair Foam Filters: These feature a 15mm thick, twin-layer foam specifically designed for our air filters. This foam is washable and reusable. For most standard road applications, where excessive dust, dirt, or sand is not common, the foam filters do not require oiling. While adding oil can provide an extra layer of protection against fine particles, it may also slightly increase airflow restriction.
• Ramair Pleated Filters: Developed with the latest in polymer technology, the synthetic nanofibre pleated filter offers excellent airflow, which in turn provides improved performance for your vehicle. Like the foam filters, oiling is not necessary, but it can be applied based on your personal preference.

In terms of airflow, the Ramair pleated filters generally provide higher airflow compared to the foam filters. However, due to their flat, pleated design, airflow can decrease as dust and dirt accumulate on the filter. Ramair foam filters, with their reticulated foam construction, can hold more dirt without significantly impacting airflow, which results in longer service intervals and less frequent maintenance.

It varies depending on the material filter you have purchased. With our pleated range we advise this to be cleaned every 3-6 months, and our foam range we advise every 10,000 miles or once a year. We offer a cleaning kit (SKU: CK-003) which comes with step-by-step instructions.

Like many things, if you don't look after something it won't last. In this case with air filters the pores of the material will become clogged, and the performance of the air filter will drop over time. Depending how long the filter has been left you might even see some signs that the filter is deteriorating.

All our filters, apart from our foam panel filters, are dry and do not come oiled.

We only advise oiling a filter if this is being used in harsh environments such as dry, hot or very dusty conditions. We would also advise to oil the filter if the car is being driven on track or is open to the elements.

Short answer is no. Our filters are not designed to be submerged in water. However, as an example if your bonnet has vents, or the filter is placed near the grill you will be fine. For extra protection a very light coating of oil will help repel any water.

Our filters are manufactured using fire-retardant foam, designed to self-extinguish if exposed to flames. In the rare event that the filter catches fire, it is typically because an external flammable substance (such as petrol) is present on the foam. In such cases, it is the chemical agent that ignites, not the filter material itself. This situation is uncommon and generally occurs only if the carburettors are not correctly set up.

No, all our filters are plug and play! However, if you're after even more of an increase in performance then a remap and other supporting modifications will work well together.

Unfortunately, this is not something we can offer. However, we have a huge range of universal cone air filters that can be purchased if we do not have an intake kit available for your vehicle.

Our universal filters are not designed to fit any specific car, but it's super easy to find a filter that will work with the space you have! All you need to do is the following:

• Measure the outer diameter of your inlet pipe (this indicates the neck size needed)
• Measure the maximum width in the space you have
• Measure the maximum length you could go
• If you have a MAF sensor, make sure this is on the inlet pipe and not the air box. With our universal air filters, you will be removing the air box, so you need to have somewhere for your sensor to go!

Once you have the above it's time to match you to the filter! All our filters have sizes in their descriptions, but we are always available on our live chat, email or phone to help!

Outer diameter is for filters that have an aluminium neck which will need to be secured to a silicone intake pipe or silicone coupler. Inner diameter is for the filters with a rubber neck which need to be secured to a hard pipe (usually aluminium) or if you have a silicone intake pipe you will need to have an aluminium coupler in-between the pipe and the filter to secure this.

We offer all our replacement filters on our website, but if you contact us and tell us what kit you have, we can advise which filter you need to purchase.

Unfortunately, we don't offer this. Our heatshields and intake pipes are only available within the full kit.

Awaiting fulfilment means that your order is currently awaiting to be packed and dispatched from our warehouse. If you have any questions please contact us via live chat, email or by phone!

Normally if the order has come in past cut off it won't be processed until the next working day. But if you give us a call, we might be able to get it out that day depending on the time and if our couriers have been.

If you are ordering from inside the USA, then no you will not need to pay customs for this part to be delivered. Our items are either made in or at least shipped from North Carolina.

Of course! Just give us a phone call and we can get that sorted for you!

Here at Ramair we are all car enthusiasts, and we know what you want. Every part of the design, testing and manufacturing of the parts is done in house here. We understand that purchasing an air filter you are after reliability, quality, and performance increases, and we deliver on all of these. Plus, you get an incredible intake sound on all our open-air filters systems!
