Alfa Romeo Owners Have Many Options with K&N Performance Air Intake System

The Alfa Romeo is an aerodynamic designed sports car considered to be extremely quick with arguably one of the greatest engines every built. The 156 are considered the flagship models.

K&N's 69-0502TWR
K&N's 69-0502TWR
K&N Engineering has released a High-Flow Air Intake System (69-0502TWR) in wrinkle red for the 1997 through 2006 Alfa Romeo 156 2.0 liter engine. See applications list below. Red is a very popular color on the Alfa Romeo in Europe.

K&N Engineers have made sure the design on this air intake system provides maximum power to meet consumer demands, by positioning the K&N Air Filter (RU-4860) far away from the engine. The large conical K&N Air Filter is designed to provide increased surface area and dust capacity. K&N's air intake design has lower restriction than the factory air box system resulting in additional power while providing excellent air filtration.

The 69-0502TWR is a two piece kit that can convert to a short ram which places the K&N Air Filter under the hood during inclement weather. When it is set up in the complete cold air intake mode the air filter is protected from road water with the use of a dry charger (included).

The free-flowing mandrel-bent aluminum tube is engineered to the specific vehicle design. The 69-0502TWR is designed to improve engine performance and is easy to install, usually in about 90 minutes or less. K&N High-Flow Air Intake Systems come with the famous K&N Million Mile Warranty.

New Motorcycle Records Set at Bonnevile Salt Flats During Speed Week with K&N Oil and Air Filters

It was at least 117 degrees at the motorcycle tech inspection stand at the Bonneville Salt Flats near Wendover, Utah during Speed Week. The Bonneville Speedway is the venue for numerous land speed records that are typically set each year.

Team Falkner Livingston arrived when the salt was still largely covered with water. “The heat was a good thing,” said Becca Livingston of Team Falkner Livingston. “Each hot day the water evaporated more and more, leaving behind two good courses. It was a great event actually, with lots of records set and only two crashes. One with injuries and one without, but luckily all were recoverable.”

Team Falkner Livingston did well and set several new land speed records. “Like all our FL race bikes, our motorcycles at the Salts were equipped with K&N Oil and Air Filters,” said Livingston. “Our CBR 600RR Honda with IHI Turbo running 650cc, Modified Partial Streamliner, Blown Fuel set a new record of 170.032 mph with FL Rider Dusty Schaller. Dusty was a rookie to the Salt this year.” Kelly Boltz, also a rookie for FL, set a new record of 152.013 mph in the 3000 cc Production/ Production class on a Rocket III.

Paul Thede of FL had a new personal best speed of 198.7 mph on a Kawasaki ZX-14. Thede set a new record of 196.604 mph in the 1650cc Production/ Production class.

Bonneville Speedway is marked out at the start of every summer by the Utah State Highway Department. Two tracks are prepared, a 10 mile long straightway for speed trails and an oval for distance runs. There is also a 4 mile long straightway for qualifying.

“The most exciting record was set by FL rider Jason McVicar of Vancouver, British Columbia,” said Livingston. “Jason is a very experienced rider who set seven new records at this year’s Speed Week. Four of those records were in the 2000cc class, and three were in the 1650cc class. Jason had a top speed run of 250.133 mph which established the first SCTA record over 250 mph on an open wheel motorcycle. We set records with K&N Air and Oil Filters.

The heat shield is engineered to isolate the oversized K&N High-Flow Air Filter (RU-4950) from engine bay heat. K&N Air Intake systems are designed to increase filtering capacity and improve throttle response while providing excellent filtration. As air passes the K&N Air Filter, it travels through the textured black aluminum tube which is attached to the throttle body. The placement of the K&N Air Intake System ensures a steady amount of cooler outside air to the engine which translates into more power.

The 2007 Focus PZEV is a partial zero emissions vehicle. The K&N Air Intake System keeps all factory vacuum operated emissions controls operational. K&N's engineers designed this Air Intake System to stay within the factory emissions parameters while producing the maximum amount of horsepower.

It takes about 90 minutes of less to install this K&N Air Intake System. It is backed by the famous K&N Million Mile Limited Warranty.
