Coming from a newbie so bear with me...and what a great site this is.

I order a Napa Filter P#6637 and went a head and did the mod to my 2001 F-350 last night. I just had a few quick and simple questions...first of...where are you guys getting the 6637 filters for $25...or am I reading something wrong. Secondly...can I clean the filter I got from Napa...or is it a throw away? Lastly...I am assuming that the extra turbo hiss I am hearing coming from under my hood in a result of the 6637 opening things up on the intake side?

This is my second mod to my truck as I recently installed a 5" muffler eliminator kit from Diesel Performance Systems Inc. finished with a 6" stainless tip...what a sweeeeet sound!!

Again...awesome site...great knowledge...and from what I have seen thus far great people!!!

Thanks!!

 

Welcome aboard PSD416. Yes there are a bunch of helpful folks here. The 6637 is a throw away, but you might extend it's life by blowing it out with an airhose. The people that is getting the filter for $25 is probably getting them from FleetFilters.com The hiss and whine your hearing is your intake finally breathing like it should. With the exhaust you have, you've got a winning combination already. Next thing is do the CCV mod. Keeps the oil off of the turbo blades and keep the boots free of oil so you don't blow them off. I give you about 3 more days and then you too will have been bitten by the "PMS" bug. (Powerstroke Mod Syndrome)

 

Welcome. Fleetfilter.com.The 46637 filter is a perishable item(can't be cleaned). Yes, the sound is normal.

 

You think it sounds cool now, go to a straight 4 or 5 inch turbo back and then it will really be neat.

 

Fleetfilter.com. The shipping was almost 10 dollars when i ordered two filters at about 20 a piece so their about 25. If you like that sound take the insulation off your intercooler hot pipe and disconnect the red vaccuum line going into the bottom of your wastegate. Sounds like you already got the pms.

 

I am also getting the wierd whiring noise coming from the turbo as it spools down, I hope that it is normal. But i am definetly impressed with the increased throtle response, but not sure on the increased MPG, they may have gone down .4 mpg or so going by the computer. I filled up today and will check again and let you know.

 

That does it, your lieometer just convinced me of what I have suspected since I first started out on my 12,000 mile journey this summer. The 6637 mod and the 4" turbo back has cost me a little bit of mpg. But I don't care, it is minimal and I know the engine must be happier being able to breathe. It makes no sense that my mpg has gone down about 1.5 mpg, but it has. I have had my truck about 3 years and I am obsessed with fuel mileage and keep very careful records and have no lieometer.

 

Yeah...safe to say I have them PMS already!!! I am doing allot of reading in here on tuners/chips..it might be my next move. I am also very anxious to get my hands on and try some of the B100.

Thanks for the tip on Fleetfilters, will check them out for sure. The Napa filter was $40. What kind of life are you guys getting out of the filters? Under normal driving circumstances...no heavy dust or mud or anything extreme like that?

As far as fuel mileage goes..without seeing the true numbers yet, I would have to say that mine have gone up with the 6637 mod and the 5" Diesel Performance Systems exhaust. I am well over my normal miles I usually get on a tank of fuel and trust me...I have had my foot into this thing ALLOT!!!

 

no, dont blow it out with an air hose. the air is pressurized up to around 100psi. the pores in the filter media are designed to stop small dirt particles but not air. when you take and use compressed air to "blow out" the filter, what you are doing is pushing these dirt particles through the filter media. now you are creating "relatively" large holes in the media, and now the filter can't do as good of a job as it should because dirt can pass right through. it kind of turns into a dust screen, not an effective filter.

if you need to clean the filter, use a shop vacuum with a small nozzle and suck the dirt from the outside of the filter. since it is at atmospheric pressure and dirt is coming out in the same direction it went in, it won't hurt the media because the dirt doesnt have to pass through it, only air.


PSD416, to answer your question, it will probably take 100,000 miles or more of highway driving until the filter itself is in the "needs replacing" condition. there is so much surface area, it takes a very long time for it to create an inlet restriction. however, most replace them every 30,000 miles or so or when they turn grey. i've had mine for 8000 miles and it's not pure white like when i got it, but yet it's not gray colored. it's halfway in between.

 

Before you get a chip make sure that you get some gauges. They are important to monitor all this power you are adding. Get a trans temp, boost, and egt gauge with either the piller mount or above the rearview mirror. They cost about 300.

 

Good point strokin_it7.3. Never thought of that. Thanks for the schooling Luckily I haven't had to clean or change mine out yet....

 

yeah, i was as ignorant about it as you until i went to school for it too. just passing on my knowledge.
