Streamline Engineering
Helene Performance specializes in high quality, high performance and high
protection replacement air filter panels and cones for select vehicles. Each
Helene Performance Baleen SE filter design is tested to the strict ISO
5011 standards to ensure they will protect your engine without sacrificing
air flow. These filters are manufactured with the finest materials
available and maintain a superior debris collection efficiency. The
Baleen SE filter will improve the respiratory function of your engine which
will result in crisper throttle response and provide nominal fuel efficiency
gains.
Using only the highest quality materials, such as premium-grade urethane
and cotton, Helene Performance filters employ a manufacturing process that
yields filters with almost no bleeding onto the filter media. This creates
more open surface area that, in turn, maximizes airflow to the engine. Helene
Performance filters also use a proprietary blend of filter media that is
layered to exact specifications which provides the fabric of this perfect
balance. Those layers are then pleated and impregnated with an exact amount
of specially blended oil to boost the filtering capabilities while maintaining
the performance of the filter. Helene Performance's streamline filter designs
along with the superior manufacturing techniques used to produce each filter,
means this air filter simply performs at a higher level and so too will your
car!

Panel Filters
Helene Performance specializes in high quality, high performance and high
protection original equipment direct replacement air filter panels for select
vehicles. Every Helene Performance Baleen SE panel filter is designed
to the specific requirements of the engine it will be protecting so you are
not getting just another mediocre one-size-fits-all design. Pleat
depth, quantity and filtering media configuration are tuned to provide the
best possible performance without compromising the protection required for
today's high tolerance engines.
The Baleen SE panel filter is the ultimate tweak for someone that wants
to maintain and improve upon the highly engineered stock intake systems.
This is an ENGINEERED filter. Not just another universal washable
filter!
Maintaining proper CFM flow and particle capture efficiency is a delicate balancing
act. Filters that flow well usually do not protect as well and vice versa. Helene
Performance has mastered the formula to achieve this elusive perfect balance
and so your engine assets will perform better without sacrificing protection. This
filter is serious equipment for serious cars.

• Easy and fast installation suitable for novice requiring only a screwdriver
at most.
• Deep multi-layered pleats increase air flow and maintain critical protection
levels.
• Maintains OEM filter's 99% debris collection efficiency per ISO 5011 standards.
• Maintains BMW engineered pressurized air box and stock appearance.

Cone Filters
The Helene Performance replacement conical filter uses the same high quality,
high performance and high protection concept as our original equipment direct
replacement air filter panels. The Helene Performance cone filter utilizes
a velocity stack formed integrally into the flange with a radius transition
into the intake pipe to help reduce turbulence. The end of the cone
sports a vortex assembly which further increases the available surface area
for filtering while also encouraging a smooth non-turbulent air flow through
the filter interior. A shelf has also been integrated into the flange
to accommodate the stock MAF screen for users that wish to still use it. Only
select applications are currently available but more are in development.
Available now for the following universal applications.
4" Inlet Flange x 7" Pleat length with Flow Vortex unit and
Lip for MAF Screen
(cross reference K&N part no: RF-1032)

The Helene Performance replacement cone provides a reasonably
priced upgrade in protection and performance for any cold-air-intake application
that utilizes this size cone filter element. Check the manufacturer's
specifications for proper size and application. New high quality attachment
hardware included.
