Another Modified Stock Airbox Thread

After searching the forum, I saw several techniques for a modified stock airbox lid. I decided to give it a try and see what turned out at the end of the day.

Supplies:

16- 6-32 x 1/2" machine screws
16- flat washers
16- nuts
8 x 12 wire mesh (a splash cover from Dollar General for $3 was used here)
1.5" Hole Saw
Drill Bit
Drill and phillips screw driver
5/16" Socket
Masking Tape
Paper
Marker

I started out by laying out the hole locations on a sheet of paper. I put my holes on 2" centers. I then centered the paper template on the airbox lid and taped it in place. I used a center punch to mark all of the hole locations. I removed the paper and drilled all of the holes with the 1.5" hole saw. I then smoothed out all the edges with a knife. I then ran a masking tape grid between the holes to serve as a guide for marking bolt hole locations. Using the center punch, I marked all of the locations then drilled them out. I cut the wire mesh to fit and then bolted it up. I like the look of the stainless mesh but black would look good too. For less than $10 and about an hour of my time, I hope to have increased airflow in the stock airbox. I ordered an AFE filter from PTP which should be here next week. We will see how it goes.

I have only set it off once running the H&S HD tune on the 300 hp setting at close o WOT. Before I would set it off at half throttle. My air intake temps have stayed the same also.

Looks good but why swiss cheese up your box when you can simply run it without the filter top on. I have been running mine topless for about 40,000miles with no issues what so ever. Running the AFE oiled filter and love it.

Not even dirt in the intake tube which means the filter is working as intended. Sure makes the intake loud. Really hear it gulping for air and the turbo whistle is much louder too.

The reason I went with a pre filter was to keep any water other debris out. Maybe not needed but I like the extra level of protection for the filter.
