Please Note - Please allow 1-2 weeks to receive your product. We don't always have our products on the shelves, and they are sometimes made to order. Thank you for understanding.
Please Note - Do not fit this kit unless your car is set up to run without the Mass Airflow Sensor (MAF-less).
PLEASE READ THE FOLLOWING INSTRUCTIONS AT THE BOTTOM OF THE PAGE! FAILING TO DO SO CAN CAUSE DAMAGE TO THE HOUSING.
We bring you our airflow technology in our MAF housings to a new MAF-less filter base, to suit builds that are not using the MAF sensor.
Kit includes
SM 90mm filter base with an integral velocity stack
Ramair Proram oversized 114mm performance air filter
Key Features
- Large Proram filter removes as much restriction as possible from the filter element of your intake set up
- Velocity stack Filter Base smooths airflow and removes air pocket restriction, resulting in gains of up to 5bhp
This kit will fit any vehicle with a 90mm Intake Kit, such as our SM Garrett Intake.
The Ramair Proram air filter in standard size is already what we hold as the best air filter on the market. The quality of the filter is unmatched by any other air filter we have ever experienced, and the price is extremely reasonable for what you get. However... we discovered in the furthest corners of the Ramair catalogue, the largest Proram you can fit under the bonnet of an Astra (trust us... we've tried them all). This Proram air filter is very unusual, it is the only Proram available in its size, and with a 114mm ID, this allows it to fit just about nothing... that's where a little Sprogley Magic comes in.
We have taken the very effective internal profile from our MAF Housings and SprogTech range, and turned it into a MAFless 114mm filter base with integral velocity stack (smooth compression of air entering the intake). This allows you to fit Ramairs massive 114mm base Proram Air filter, which would otherwise be impossible.
This kit should fit any 90mm intake kit, including our own Garrett kit. It is now available as an option with our Garrett Intake Kit.

Instructions
Failing to correctly install our MAF housings can cause damage such as cracking / splitting. These MAF housings have been tested thoroughly, both by ourselves and independently. They are more than strong enough for their purpose, and will only break if not installed correctly. we WILL NOT replace or refund any MAF housing that has clearly been damaged due to incorrect installation, so please read the following instructions and take care during installation.
Screwing the MAF sensor into the housing (Not required for MAF-less filter base)
When installing the screws into our MAF housing, it is important to take care to avoid cracking the sensor boss. The screw thread needs to be cut inside the hole. This can be done by gently turning the screw in 2 turns, followed by turning back out 1 turn. We have installed countless sensors into our MAF housings this way, and never once caused the housing to split.
Connecting your silicone pipe to the MAF housing
Due to the rough surface of the 3D printed part, silicone pipes grip onto the housing very well, without any clamping force from a jubilee clip. We have deliberately made the fit very snug for this reason. The jubilee clip is simply a safety measure to ensure the MAF housing can't possibly slip out of the silicone pipe. Because of this, the jubilee clip only needs nipping up. It is important to remember that the air inside your intake is a vacuum, not positive pressure. By gently nipping the jubilee clip up, you will not damage the MAF housing. If the jubilee clip is aggressively over tightened, it will cause the MAF housing to crack. This amount of pressure is completely unnecessarry.
Please take care with installation.
