Does a cold air in take damage the turbo? Thanks to all that help.

 

depends on the filter, around here the filter of choice is napa part # 6637. and the one to stay away from is K&N other who know more on the subject will chime in soon, o and btw welcome to FTE!

 

Welcome to FTE!

A cold air intake does not damage the turbo.

 

No, unless you run it w/o a filter on it!
K&N should be avoided IMO... they have known issues with dusting. AFE, S&B, and a few others make quality kits. Bang for the buck though, you can't beat the 6637 filter (although it's not a cold air kit).
Its been debated on here whether or not you gain anything from a cold air setup, you might want to do some searching before you spend your $. Good luck, and welcome to FTE!

 

Welcome to FTE.
Tell us more about your truck.We can get you hooked with the Mod bug and help spend your money!...6637 W/Pete's cover is a cool set up.Talk to Riffraff(Clay)he has some great deals

 

 

Curoius why stay away from K&N? I have an AFE but I am getting ready to clean and oil it with the K&N filter charger cleaner and oil. Is there an issue there?

 

K&N's are notorious for dusting, especially the filter that drops into the stock air box. When I bought my truck, it had a K&N in the stock airbox, and when I took the top of the airbox off this is what I saw:



The K&N intake kits seem better, but I still don't trust 'em.
You might do some research, I think AFE recommends their own oil and cleaner for the filter. It probably doesn't matter much, but I know in the dirt bike market one aftermarket brand of filter was prone to coming apart when used with another's cleaner and filter oil. I'd hate to see you disintegrate your AFE filter!

 

Double post...

 

Thanks chase, I'll research it further

 

There are two basic ways to get more airflow through a filter:
1. "Open" it up so it flows more air, or
2. Make the filter larger

Obviously, you can do a combination of the two. The bottom line is that you have to reduce the air flow restriction to get more air into the filter.

There are some ways to increase a filter's open area and not necessarily compromise it's filtration efficiency, but that is done MOST successfully by increasing it's size, even though some changes in filtration media (from paper to foam, etc.) can accomplish varying degrees of this same objective.

K&N has made a huge impact on the automtive market by getting more air to the engine, most typically in gas engines where some slight levels of ingested dirt/dust are not necessarily as harmful as is with our turbocharged diesel engines. Chase has already stated how many folks have inspected their intakes between the K&N and the turbo only to find evidence of plenty of dust getting through.

I have to also say that an improperly sealed filter element will let in as much or more dirt than a poorly designed filter element, as has also been seen on some stock Ford intakes where the elements would not maintain a proper seal (for various reasons).

The problem with the ingested dirt in our turbos is that the turbo wheel is spinning in excess of 20,000 rpm and has extremely high air velocities flowing thorugh it. When you add abrasive dirt into that air stream, you end up sandblasting (or dusting) your turbo wheel to the point where pieces of the wheel can actually break off due to the thinning and high speed spinning forces. This same phenomenon is not typically a problem on gas engines, but can (and has) cause(d) the death of numerous expensive turbochargers in our diesel engines.

EDIT... there is a THIRD way to get more air through the filter, and that is to pull harder with a larger turbo, but that's not at all what we're talking about in this thread, so I'll leave that alone.

 

Great post Pete!

 

Ditto, great post
