K&N Intake on Triton V10

DandV · 10-06-2017, 03:28 PM

We have a 2006 Jayco Greyhawk 30GS and dolly tow a 2008 Saturn Vue. Gas mileage is about 6.5 mpg or 8 if not towing. I was just wondering if anyone had installed a K&N intake and if it improved their fuel mileage enough to make the $380. dollar price tag worth it? Like many RV'ers I usually just put the nossel in and fill it up without paying much attention, but in the interest of economics I feel I should at least consider this.

Thanks
Dick

I can't speak to the Greyhawk in particular, but every vehicle I've ever had since I was 18 yoa, has had a K&N intake/filter. Too me the reusable filter alone has been worth the cost! I just put it on my Ram 3500.

I put one on a mid sized PU several years ago, and all it really accomplished was creating a "roar" or low growl when I hit the gas pedal hard. I grew tired of the noise. MPG might increase a 1/10th or 2 depending on conditions. GH's have plenty of power to move the unit down the road and up most if not all inclines. I would just another tank of gas, JMO.

You will never recoup the cost in fuel. In a NA engine like the V10 there is minimal performance gains and zero mileage gains. On a forced induction motor you will see a mild performance gain. As bookedemdanno pointed out, though, there is something to be said for never having to buy another air filter again.

Consider buying a K&N drop in filter for your factory air box- much cheaper and pays for itself after 2 or 3 filter change intervals.

You will hate all the new engine noise, that rush of air gets very annoying. Save your $380 and put it in the fuel tank for more enjoyment.

Google K&N filters and "dusting".

I use to live a 1/4 mile down a dusty road. I tried the K&N in my Cummins diesel. After a week I inspected it and I could draw pretty circles in the dust on the inside of my intake so I took it out. The K&N filters we're originally developed for race track use, not highway use, to keep the bigger clods of dirt out. Those guys don't care about engine wear. If you want more power my own opinion is get the Banks headers. It's the only thing that actually worked for 1/2 mpg better and more oomph for me.

Thanks all for your input. I think I will put the $380 into my tank and not worry about it. See you on the open road!

All it did for us was add to the noise level in the cab. There was no change in fuel consumption, and no noticeable improvement in engine performance.

K&N filters are much less effective at removing contaminants than regular paper filter, and for this reason alone I won't use them in both my daily and off-road vehicles. Besides, new vehicles are finely tuned, and the flow difference might set off engine codes.

As stated above, they are only good on a race engine that you aren’t all that concerned about filtration. They do not filter as well as a paper filter, if over oiled, which is pretty easy to do, the excess oil can ruin your MAF sensor, and have been shown to be harmful on the Cummins turbo diesel (so I’d do a bit of research on dusting Bookemdanno and consider putting the oem setup back on your truck).

Awesome...one more thing of me to research! Thanks for the info.

Another option is something similar to the AEM dryflow.... an open flowing filter without the K&N oil. I've had one on my tweaked 12V Cummins with a prefilter sock for 25000+ miles of hard commercial towing and plowing with zero ill effects.... and the truck screams.

I can confirm that the K&N Filters are complete and total garbage. I had one on a 5.3L Vortec that completely destroyed the MAF Sensor, gummed up the EGR with fine particulate and fouled the plugs, which in-turn put raw gas into the catalytic converter, ruining it.
For the few extra HP you 'might' get out of one, IMHO, they are completely worthless.
