If you want to optimize the air flow, especially with regard to extremely high horsepower, you are well served with a tuning air mass meter. The air mass meter (air mass meter adapter) ensure optimal air throughput even with outputs of more than +400 PS. Both air mass meter adapters and complete air mass meters (including sensors) are commercially available. The articles are presented in more detail below and important purchase criteria are mentioned.
Air mass meter adapter - what does it bring?
The adapters can be customized aspiration are considered, which are used in addition to standard air mass meters. The articles are installed in vehicles with tuned engines and represent a way of ensuring sufficient air throughput with high horsepower. But you have to be aware of the different implementations. An individual air mass meter adapter (adapter housing) enables, for example, the installation of a specially made / individual intake in the vehicle. And yet in cars where the air mass meter is normally installed in the original engine cover, the standard LMM can still be used. The adapter housing is then adapted to the desired specifications. Alternatively, there is also the possibility to replace the complete LMM including the sensor. Here it always comes down to that Vehicle and Objective
How are air mass meter adapters constructed?
The modified LMM have a high quality adapter housing. When buying, you have to pay attention to high precision and a CNC milled component if possible. If the adapters are made with high precision, then they ensure an optimal and significantly improved flow. Furthermore, they can be purchased for many vehicle types. It is important that the adapters have smooth surfaces. The smooth surface creates an even air flow. Possible turbulence can be reduced to a minimum. When buying an adapter, care should also be taken to ensure that the internal diameter is sufficient. For example, a 70 mm inner diameter can provide sufficient air throughput for a +400 PS four-cylinder with a displacement of approx. 2 liters. As mentioned, you always have to consider the engine, the additional power and other components of the planned increase in performance.
Why may an upgrade be necessary?
For example, if you have a larger one turbocharger including chip tuning, etc., you should upgrade the air mass meter to achieve an optimal result. The modified LMMs handle higher air masses. The articles are available for many engines and vehicle types. For example, if you want to provide the popular 1.8T engine from VW with a larger turbocharger, you almost always need a suitable air mass meter. Variants with square or oval plugs are available on the market. The choice of connector depends on the motor type. For example, square plugs can be used for 1.8T engines that are older. While newer 1.8T engines require an oval connector. The electronics are also decisive for the choice of connector.
What needs to be considered when buying?
If the air mass meter is upgraded, then the automotive part should match the engine, turbocharger and vehicle type. The dealers and manufacturers usually state for which vehicles, engines and turbochargers the respective item is suitable. When purchasing and upgrading the air mass meter, the software may also have to be adapted to the higher flow. However, the manufacturers and dealers provide corresponding information in the product descriptions. It should be clear whether an existing air mass meter adapter is sufficient or a new air mass meter needs to be installed.
We hope that you the info report on the topic / term Air flow sensor (Further designations / keywords: air flow meter, LMM) from the field of autotuning. Our goal is that the largest German-language tuning dictionary (Tuning Wikipedia) and to explain tuning terms from A to Z easily and understandably.
