Overview:

Update the fuel system in your Dodge truck with a high performance in-tank EFI fuel pump module. These fuel modules fit inside the factory tank & feature a billet aluminum flange, Hydramat®, fuel sending unit, and high performance pump. Choose from 255 or 450 LPH (liters per hour) fuel flow & return style or returnless design. The amazing HydraMat® is Holley's patent pending design that solves the problems associated with traditional fuel pick-ups in stock fuel tanks as well as racing fuel cells. During hard cornering, acceleration, stopping, inclines, and low fuel conditions fuel runs away from the fuel pick up which introduces air into the system resulting in poor engine performance and even stalling. HydraMat is the solution! Direct Fit in the following Vehicles: 1997-2004 Dodge Dakota (2WD & 4WD) 1998 Dodge B1500/B2500/B3500 (Full Size Vans) 1999-2003 Dodge Ram 1500 Van/Ram 2500 Van/Ram 3500 Van (Full Size Vans) 1998-2003 Dodge Ram 1500/Ram 2500/Ram 3500 (2WD & 4WD Full Size Pickups) 1999-2001 Dodge Ramcharger (2WD & 4WD - Mexico Only) 1998-2003 Dodge Durango (2WD & 4WD)

Better than Honda Cabin Filter for Allergies -
Size: 8.3" x 9.3" x 1.3"
Installation took all of 3 minutes. Noticeable improvement in air quality (less allergy response) since installation. Others mentioned a reduction in air flow but have not noticed a change. ,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, Update (9/2020) Noticeable reduction in air flow. I have needed to increase the fan speed to make the cabin comfortable. I may be switching brands soon. I will pull the filter at 6 weeks and see if it is getting plugged (yikes). //////////// Update (10/2020) I pulled the Bosch filter expecting it to be plugged due to the lack of air flow. I was surprised to see it was clean. There were are few small pieces of stuff in the folds of the filter but only about 10 of them. I held the filter up to the light and then tapped it on white paper to see what would fall out. There was nothing present to explain the extreme loss of air flow. I have used Bosch cabin filters in my other vehicles (not HEPA) with great success. I was hoping to help the allergies of my family but having to run the fan on high to receive any airflow was more annoying than helpful. The noise was irritating and the air flow was still less than the Honda filter I removed. I purchased a new Honda cabin filter and our van is back to normal. I did not realize how much I missed the auto temperature setting. I was setting the temperature about 5 degrees below "normal" to try and keep the temperature consistent, and it was not during the hotter summer months. Unfortunately I am beyond the 30 day Amazon return window so I am not able to return the cabin air filter. :-( This is my first Amazon review that moved from 5 to 1.....

Reliable part
The price of this item was a bit of a shock. A good one though. I gave it to my mechanic, he installed it with no problems. Runs just fine. Would buy again
