So, I struggled with the decision on mounting "grill LED" and talked with ZROADZ about their ideas, see below
Unfortunately, even thought the fit and finish seems nice, by blocking the air intake for the radiator and the additional cooler on the drivers side is no in my opinion in any climate a good idea, so I embarked on a solution,
I bought the zroadz light but unfortunately I don't get my truck for another 43 days. Had to pick them up though while I was able to get $45 bucks off of them.
As per my original assertion, I have a better air flow vs the zroadz inserts, I am respectfully not able to display the actual tests, however I will comment that the grill inserts absolutely block air intake, that is understandably the only comparison I was making, and yes, my LED bumper mounted LED lights do interfere with airflow, yet the difference is minimal compared to the grill inserts by zroadz.
