K&N (57-1570): Air Intake System for ’14-’15 Jeep Grand Cherokee 3.0L V6 EcoDiesel

The 3.0L V6 turbo engine in 2014–2015 Jeep Grand Cherokees provides a modest amount of power but is paired with a stock air intake system that may cause unnecessary air turbulence and slow the volume of airflow reaching the engine.

K&N has your answer. The 57-1570 air intake system is engineered to replace the factory air filter and air intake housing. Its free-flowing, roto-molded, high-density polyethylene tube is meticulously designed to be aerodynamic—and when paired with the included oversized conical air filter can increase airflow to your engine by up to 50% (the filter is washable and reusable to boot). You’ll enjoy up to 100,000 miles between cleanings under normal highway driving conditions.

K&N’s 57-1570 system also offers a black powder-coated aluminum heat shield, protecting the air filter and intake air from hot engine bays. The air intake tube funnels airflow directly into the engine’s throttle body for a guaranteed increase in horsepower and torque; in fact, dyno testing of a 2014 Grand Cherokee saw an increase of 12.67 horsepower and 30.94 ft.-lb. of torque.

Features

  • Guaranteed to increase horsepower.
  • Designed to improve throttle response and engine sound.
  • Lasts up to 100,000 miles before service is required (depending on driving conditions).
  • Replaces entire factory air intake system.
  • Free-flowing, high-density polyethylene tube.
  • Washable and reusable lifetime air filter.
  • Installation: < 90 minutes.
  • Warranty: K&N Million Mile Limited.

Driven Racing Oil Tech Bulletin: CK-4 Diesel Oil Wear Warning

Editor’s Note: Our friends over at Driven Racing Oil produced this technical bulletin alerting consumers to the possibility of increased wear issues related to the new CK-4 diesel oil formulation. To find Driven Racing Oil products at your nearest Parts Pro™ affiliate, see our Store Locator.

Driven Racing Oil CK-4 Diesel Oil Update

Diesel engine oil makers recently changed from the decade-old CJ-4 formulation to the new CK-4 formulation. While intended to be an upgrade, the new CK-4 formulation has been met with resistance and even an outright “do not use” warning from Ford Motor Company.

Just before the new CK-4 specification went into effect in December 2016, Ford Motor Company issued a service bulletin stating that Ford 6.7L diesel engines should not use the new oil, citing identified wear issues. In fact, Ford also issued a new oil specification closely aligned with the previous CJ-4 formulation and called for its use in Ford 6.7L diesel engines. So what’s going on here?

Previous API diesel oil specifications, like CJ-4, had to pass the ASTM Sequence IIIG valve train wear and oxidation test, which measures flat tappet cam and lifter wear as well as other parameters. This is not true of the new CK-4 specification.

Diesel engine oils have historically contained higher levels of the anti-wear additive ZDDP. With more oil marketers wishing to supply “universal” oils that meet both API SN requirements for gasoline engines and API CK-4 requirements for diesel engines, the levels of ZDDP have dropped in some CK-4 oils. Without the Sequence IIIG flat tappet cam wear test, it appears that some of these lower-ZDDP diesel oils are causing increased wear in diesel engines. This should serve as a word of caution for all users of diesel engine oil—regardless of whether you own a 6.7L Ford.
