K&N Air Filter

  • Finally an air filter with promise

    K&N air filter for optimal air flow

    Air flow with a standard air filter

    Air-filter tuning in a nutshell: Your engine needs more than 12,000 liters of air to burn a single liter of fuel. K&N car air filters feature patented high-flow technology to help you reach maximum power. They ensure that sufficient air is always available in the best possible quality for optimal combustion. This further increases combustion efficiency, pistons and cylinders have less strain, and the engine sound is noticeable better.

    K&N air filter – more air flow with higher filtering quality

    Better performance comes with lower costs. Because K&N car air filters are made of a special cotton weave, they can be cleaned without sacrificing quality. This makes maintenance costs considerably lower. As the official air filter of the NASCAR series, K&N has gathered one-of-a-kind know-how. K&N guarantees the performance of its air filters for up to 1 million driven miles.

    Major features of K&N air filters.

    More Power (1-4 HP) And Torque

    Improved Engine Sound

    Positive Fuel Consumption Benefit

    1 Million Mile Warranty

    Low Maintenance Costs

    Easy Self-Installation in 5 Minutes

    More Power (1-4 HP) and torque

    Exclusive, patented High-Flow technology is used in K&N air filters. It maximises air flow and ensures that the engine is supplied with a maximum amount of air for combustion in all conditions. This creates the ideal air/fuel mix in the cylinder – the result is greater efficiency in your engine and, thus, more power and torque. The performance increase is typically around 1-4 HP.

    Improved engine sound

    The patented technology in K&N air filters maximises the amount of air that flows through the filter textile. The increased air volume creates a stronger intake sound, which is characteristic of more powerful vehicles. Your engine sounds noticeably fuller and sportier.

    Positive fuel consumption benefit

    An air filter should supply the greatest amount of clean air possible to your engine for combustion. K&N sport filters provide an extremely effective filtering effect without unnecessarily hindering air flow thanks to their special construction. This lowers friction losses in the movement of the pistons and improves the air/fuel mix in the cylinder. This leads to improved efficiency levels and, as a result, to lower fuel consumption.

    1 million mile warranty

    The global market leader K&N provides a “Million-Mile Limited Warranty“ for all of its car air filters. This warranty demonstrates the premium nature of K&N filters. They last a vehicle's lifetime.

    Low maintenance costs

    K&N car air filters consist of a specially processed, oiled cotton textile that is arranged between an aluminium wire mesh. Thanks to the special treatment the textile can be easily washed with K&N cleaner and air filter oil (or with similar products). This means the air filter can be used again and again without any quality losses. This dramatically lowers maintenance costs.

    Easy self-installation in 5 minutes

    You don't need any specialist skills to remove your old air filter and install a new K&N car air filter. You can finish the replacement with a few simple steps in a couple of minutes.

    The technology is invisible, the difference is tangible

    Here's why air filters are so important for modern vehicles

    The smooth operation of today's sophisticated engines depends on every little thing. For example, tiny dirt particles in the air required to burn the fuel: the fewer dirt particles that make their way into the combustion chamber, the less friction loss between piston and cylinder and the less wear and tear. At the same time, optimal air/fuel mix in the combustion chamber is decisive for power and torque. K&N high performance air filters are distinguished by supplying even the largest air volumes in the required purity at any time

    Preparation

    Unlock the bonnet of your vehicle

    Locate the air filter box

    Our example depicts a 2.0 TDI engine from Audi. The air filter box is in the bottom right corner of the image.

    Open the air filter box

    Open all screws with the correct tool

    Take off the cover of the air filter box

    After taking out all the screws, you can lift and remove the cover of the air filter box.

    Remove the original filter

    Now you can remove the original air filter from the housing.

    Insert the K&N air filter

    Take the new K&N air filter our of its packaging and insert it into the air filter box.

    Close the air filter box

    Now put the cover back on the filter housing and tighten all screws.

    Attach note sticker

    Attach the K&N sticker in a prominent location on the air filter box so as to indicate to the workshop that a swap is no longer necessary.

    Final steps

    Remove all objects from the engine compartment and close the bonnet. That's it. Have fun driving!

Help differentiating CR/PD

Distinguishing between Common Rail (CR)
and Unit Injector (PD)

Applicable to certain Volkswagen AG model series with 2.0 TDI engines

Several Audi, Seat, Skoda and VW model series with 2.0 TDI engines use both CR and PD ("Pumpe-Düse" / Unit injector) technology. RaceChip chiptuning is specially customized to the applicable fuel injection technology with respect to both hardware and software. If your vehicle is specified in the list of applicable models below (all other 2.0 TDI models feature just one type of technology), it is important to determine, before choosing a tuning product, which type of injection technology is installed in your vehicle. For such models, you will therefore find the “CR” or “PD” designation after your engine code.

PerformanceThe following Volkswagen Group model series are applicable:Engine code CREngine code PD
100kW (136hp) Audi: A3 (8P), A6 (C6)
VW: Golf Plus, Jetta V, Passat B6
CAGB, CBAA, CFFA AZV, BMA, BNA, BRF
103kW (140hp) Audi: A3 (8P)
Seat: Altea (5P)
Skoda: Octavia (1Z), Superb (3T)
VW: Caddy (2K, 2C), Eos (1F), Golf V,
Golf VI, Jetta V, Passat B6, Touran (1T)
CBAB, CBDB, CFFB,
CFHC, CJAA, CLCB,
CLJA
BKD, BKP, BMM, BMP

If your vehicle is in this list and you are not sure if it is a CR or PD version, then simply follow one of the following steps to identify CR or PD technology.

Using the engine code:

For PD models, the engine code consists of 3 characters, while for CR there are 4 characters. You can find your vehicle’s engine code in the specification sheet in your service booklet or on the data sticker in your engine bay.

Using engine images for CR and PD:
