Timing Belt Idler (LH Cogged Pulley) 260-4701 The filtered air flow is

The filtered air flow is funneled through a CFD-designed velocity stack minimizing turbulence and through an air flow straightener grid before passing through the mass air flow sensor

The ECU compares the rear oxygen sensor signal to the front oxygen sensor signal to determine if the catalytic converter is operating efficiently

The swaybar (stabilizer) end link connects the swaybar to the control arm

This process helps to maintain the main bearing bore geometry under extreme forces and reduces the possibility of bearing failure

Timing Belt Idler (LH Cogged Pulley) 260-4701 The filtered air flow isTiming belt idler pulley with toothed surface used on the LH side of the engine. Uses a double row bearing design. It is recommended to replace these pulleys at normal timing belt intervals because the grease in the bearing often dries up causing the bearing to feel rough or be noisy.
