Do I Need a New Air Filter When I Delete DPF?

I've been reading a lot of posts and I noted some that say you need to get rid of the stock air intake when you do a DPF delete. Is this true? If so, any recommendations on brands?

Thanks!

On some of the higher horsepower tunes yes. I think Spartan says on their 275 or higher you do. I also read it on some other tunes companies.

If your running a 6.0 PS. the stock air box is all you need up to @500HP. Keep it........Steve

This is the 6.4 section.

You need an intake or drop in filter with our 250 and up tunes. The 210 and under tunes can be used with the stock filter. Not sure on the other tuners though.

You can get by with the stock intake, but an aftermarket kit is HIGHLY recommended for the extra airflow. In the higher tunes, you will get a "Check Air Filter" on your dash if keep the stock setup.

Thanks, guys. I have the 6.4. (Need to fill out my sig!) DSTRBD - This is Chad from dieselplace. Just got rid of my Duramax and now I'm tuning up my F250. I don't think I'll be running a big tune. Probably just a tow tune.

I know with my old Duramax, the stock airbox was the way to go. Any suggestions for the F250? I have heard the stock setup is extremely restrictive.

THANKS!

Whats up man, how you been?

The stock airbox on the 06-10 Duramaxs do a pretty good job, however, the 08-10 Ford airbox just cant flow enough, especially in the hotter tunes. You will be able to feel a difference with a new intake on the 6.4L. I recommend S&B or AFE, both make excellent kits.
