Right now I using a K&N filter in the stock set up. How much of a REAL difference if I change to a BHAF and where do you put it? I've thought about adding additional air vents in the stock intake but I don't want to butcher anything until I'm sure. I'm also using a banks exhaust 3" to muffler then 3.5 to the rear of the rear tire. I've thought about going straight pipe or going to 4" exh.. Any of you using a straight pipe with a stock length set up?

I'm new at the dieseling and appreciate your opinions, Thanks

 

what is a bhaf???

 

Big Honk'in Air Filter ~



Most install it in the same location as the OEM air filter box.

The filter itself won't do much for a bone stock truck. HOWEVER. The additional air flow afforded by the filter will allow one to add more fuel without the EGTs going up too high ~ meaning more power.

The increase in the exhaust system roughly equates the same plus improvements in turbo spool. It's my understanding the biggest bottle-neck in the exhaust is right where the exhaust plumbing goes over the rear axle followed by the TOP (turbine outlet pipe).

Hope this helps.

 

Are these the right part#s Fleetguard AH19037, NAPA 2790? When I did a search I came accross a couple different part numbers. Is the NAPA product as good as good as Fleetguard.

 

so take it no one really likes K& N then???

 

I 'spect the fact of the matter is, most of us started with the K&N (I did ).

While, for its size, it does flow a lot of air, . . . but it's at the expense of more trash getting through. I ended up dumping mine after discovering some impact damage to the leading edges of the turbos compressor impeller.

 

Thanks for the help.
