These under shrouds were developed to protect your critical engine parts under the car and also because the cheesy plastic OEM shield deteriorates over time and usually ends up on the highway behind you somewhere. Without the shield in place the air that comes in thru your facsia should be directed into you radiator and instead will just take the path of least resistance and exit under the car instead of cooling off your radiator. Just like the upper radiator air guides keep air going thru the radiator,

The bottom is even more important to have in place as it is much easier for air to escape there. The ZSpeedperformance under shroud will help give the lower front fascia much more rigidity also, As you probably know, running without the shield in place at high speeds can do serious damage to the front fascia as it will droop down and can rip apart. The BEST feature of all thou is that you can actually change your oil AND filter without removing the entire shroud.

I have integrated a oil change access door into the shroud so all you have to do is remove 2 bolts and you have ample room to get to the oil filter and drain plug 

Weight on the entire piece is 4.5lbs, The plastic OEM shield for reference weighs in at a bit over 3lbs. Very lightweight and much more protection!

 These no longer have the ZSPEED logo cut out in the middle.
