Leave it to K&N
to come up with products
that have both cosmetic appeal as well as deliver outstanding performance. K&N's
Carbon fiber composites have attractive cosmetic appeal, and the outstanding
stiffness to weight ratio that is needed to stay competitive in today's racing
industry. Carbon fiber composites have taken the method traditionally associated
with fiberglass and perfected it to a precise science with outstanding performance
as the result. The process of advanced composites controls resin and fiber content
to exacting tolerances. Though traditional methods have proven successful in
producing a variety of products; advanced composite products can be engineered
considerably stronger and assembled with even greater accuracy. K&N's Advanced
Composite Division offers products to really get excited about.
Carbon fiber, as a
raw material, has been treated to handle heat from below 0 to 2500 degrees Fahrenheit.
In most cases the limiting factor is the matrix or resin system, not the reinforcement
material such as carbon fiber, fiberglass or Kevlar. Epoxies are no longer a
simple brush on mix of basic compounds. Chemists have spent years maximizing
the function of the matrix by blending epoxies with ceramics and a number of
other ingredients. It is a precise science where strength, durability, function
and temperature all have to be considered. Our products are engineered with
specific resin systems for application specific needs. These products must take
into consideration such things as: fire retardant resins, ceramic blends to
handle high heat and flexible systems for damage tolerance. This same kind of
consideration goes into everything K&N makes.

All K&N Universal Air Filters
K&N Universal Air Box Assemblies
|
Light weight yet durable,
K&N's Universal Air Boxes are a must for any racer currently using
traditional multi-siamese stacks. Constructed from ultra-light weight
carbon fiber and weighing in at just under 3-1/2 lbs, K&N's Universal Air Box Assemblies provide ample air flow for your racing needs.
|
If maximum airflow is what you are looking for, this airbox is your ticket,
flowing at
up to 2700 CFM. K&N has constructed the base portion of this assembly from carbon fiber to fit from 2"to 2-5/8"
Hilborn, Kinsler and Engler stacks. This allows you to do away with clamping a filter on to each individual ram tube. Once the base has been put in place, simply slip the main filter assembly over the stacks. Easily done and at only 3.4
lbs., this airbox will allow your vehicle’s engine to breathe all the clean air it needs to make you a winner.
These air box assemblies are used on sprint cars as well as other racing
vehicles where light weight and high air flow are desired. As with all K&N
air filters, universal air box assemblies are washable and reusable air filters. Simply use
K&N oil and cleaner to service your filter.

This ultra strong and light carbon fiber scoop was
designed using computational fluid dynamics (CFD). This design
provides an 18 lb. decrease in drag. The K&N scoop also produces
more even air distribution inside the scoop, which helps naturally
aspirated engines run better and produce more power. In addition to NHRA's
Pro Stock class, the scoop can also be used in Super Stock, Super
Gas, Top Sportsman, Pro Mod classes and other
racing applications.
