Towing CAI Question

[kd4crs]

All the CAIs I tried made that horrible drone while towing our travel trailer. It was so loud you could not talk in the cab without yelling. That is what led me to develop the DWV intake mod. Check this out: http://dygytalworld.ehost-services13...l#faq_snorkel1 You get a little power bump from it and it keeps the factory noise dampers which makes it tolerable while towing.

Either the gryphon with custom tunes.

Or return back to stock and AEM dryflow drop in filter with the gotts/dwv mod.

Personally, the both of them. Just get rid of cai. The only reason I say this if the k+n ever gets over oiled after cleaning, it might lead to the maf sensor getting screwed up. That goes for any oiled filter.

I don't know if that is a true statement:
K&N Response to Mass Air Flow Sensor Concerns
That page has some video links describing some in house K&N testing regarding exactly this. They couldnt break a MAF even after submerging it in oil.

It is not that the oil breaks the sensor, the problem is the oil is said to coat the sensor and mess up the readings.

I don't think you clicked any of the video links on that page I linked earlier...

Out of 107 sensors returned: 65 functioning properly, 19 completely dead, 23 malfunctioning. Of the 23 malfunctioning, none had any evidence of k&n oil.
Mass Air Flow Sensors Intro & Test Results Summary

Test bench: 1000 CFM for 3 days straight using a 30% over-oiled filter = No oil loss from filter.

Dunking the MAF in a beaker of oil, initial readings were off, but sensor returned to normal operation after a few cycles.

I think this myth is what Adam and Jamie would call:
BUSTED!

How conviniant that K+N just so happens to use the GM mass air flow for its testing.
Also their tests are biased due to that they performed them and did not have third party intervention.
I challenge you to find third party testing before you announce BUSTED!

Why would the car brand make any difference? The same K&N filter technology & same oil is used on all their filters...

As for 3rd party testing, how about the 107 supposedly defective sensors that were returned to them, 65 were totally fine! They sent the 23 malfunctioning ones to an independent lab (3rd party) to examine and determine contaminants. NONE had k&N oil on them. This is all from the first video link I provided earlier.

What about the millions of other filters they have sold over the years? Just think of how many millions of miles have been driven with their filters? How more unbiased a study do you want?

I have a technical background, I work in a lab, and I do a lot of testing according to standards. So I can appreciate when a company spends the time to do the R&D, with a dedicated test fixture, with annually calibrated instruments. You won't even find that at Mythbusters...

This myth is busted, IMO

I'm not saying you or K&N are wrong.

That is just one of the general opinions and like many general opinions can be supported or rejected just as easily.

Also like I said, when I installed my drop in filter I did notice an instant improvement so they do have a good product. I have no problem with oiled filters because I've been using them for years on everything from gocarts and motorcycles to large diesel tractors and havent had a problem with them yet.

That's an interesting link, Keebler. What I like about it is it seems pretty "calm", clear, to the point and was written by someone who knows how to write (at least the couple pages I've read so far). It makes me want to believe them.

Another thing I acknowledge is that "Bluejay", another Mod on f150online has been using a K&N drop in for years with no problems whatsoever. I suspect they DO have a product that works, although I can't really decide if it works any better than the OEM filters.

I have a K&N drop in filter and I did notice a slight improvement after installing it. I'm sure that gain is from having a little bit less filtration. I dont really care about what advertisers say about that because I can look through my filter and make out objects. It is however still filtering quite well and greasy spots on the inside of the intake are dark but still pretty clean.
