K&N problem???

[dieseldan2005]

Say i just picked up my truck from the dealer and i was talking to my salesman and he said not to buy a K&N filter cause over time they warp and pull up into the intake tube and let sand and whatever into the motor causing motor failure. They have had some 7.3's that have blown due to this. What do you guys have to say about this. Anyone know of this happening and if so are there any filters that dont warp?? So i don't have to buy a different intake.

Just do a tymar type intake and ditch the factory air box...

Yes, K+N filters do not seal well to the factory air box... Known problem for a long time...

Or you can get the best and get a AFE stage 2...

The AFE won't let hot air back into the engine? I'm just wondering cause it looked like an open top. But hey you guys that already have them would know best. Let me know how they work and maybe i will consider one. I have just heard that the cold air kits let too much hot engine air back into the motor.

the hot air isnt the problem...its the poor level of filtration and the lack of sealing allowing small particles through wich will damage your turbo and they cylender walls...

Someone's been reading too many Banks ad's...LOL

The open intakes see a 2-3 degree temp difference when moving at 30 MPH, this is the open ones like a Tymar and such...

The intakes with a heat sheilds are less then that! Banks leaves this little bit of info out of there add's... They do there tests sitting at idle in a hot parking lot...

AFE stage 2 I can say with 99% accuracy is powering all the HI HP trucks out there... Here is a pic...

marc were you refering to the K&N? Cause thats exactly what my dealer told me would happen with the K&N. So an open air element isn't really a big deal? I just hear both sides of the story so i just wanna make sure i get it right the first time.

K&N....i wouldnt even run one of thier full intake setups myself.....honestly i wouldnt run anybodies but AFE, a tymar, or a sever duty airbox (donaldson)

No i never look at banks stuff i can't afford it. The guy at my local parts store was telling me about the ahem "HOT AIR" so i trust you guys more thats why i posted this thread. One more question does the open air let water in?

hopefully...LOL..

The sized particles of water that can actually make it through a filter are so small, that they actually will be benificial to the motor (similar to water/methanol injection on a smaller scale) in the end, not to mention the heat from the turbo is going to vaporize it anyway...
