Just looking for some opinions on the best aftermarket airbox upgrades for an 04 Hemi Ram. Ive seen K&N FIPK, Airaid systems and volant ram air kits and was wondering how the systems compare on a performance basis. I dont really care about price, just want to know which one makes the biggest difference. Any info would be great.

 

I just put the KN FIPK on my 4.7 and WOW did it wake it up. I got it new off of an ebay seller, was like $230 shipped.

 

I threw on a 77 Series FIPK from K&N and got it off Ebay for about $50 cheaper than anywhere else. As for performance gains, I can't really tell in HP (cause the good ole @ss-dynometer isn't quite that accurate) but I've gained a solid .5 mpg better and often 1 full mpg better. If you get the K&N get ready for some ticking sound to be coming from the intake, don't worry, its just the sound of the cylinders firing on the passenger side coming through the EGR Valve into the Throttle Body and out through the Intake pipe.

 

Hello WingViper

I found your post regarding the ticking sound as a result of putting in a K & N filter. Well i seem to have the same problem but not sure what is causing it.

I have a 2000 Dodge Dakota QC 4.7l and it's only since i put in the K &N filter that i noticed this ticking, it was first only when i first started up the truck, but not that the temperatures are droping(-20c) it seems to be ticking more often, Im thinking it has something to do with the cold air?

This K&N filter is just one of those replacement ones that fit into the factory air box. But i would assume with the less restricted air , i may be having the same problem you had mentioned.

It appears to be coming from the passengeer side of the truck.

I was just wondering if you had heard of this happing on the 4.7l engine.

What i will do is put the non k&n filter back in for the winter and see if it helps any

Thanks

Glen

 

A post on another forum where several intakes were compared on the same dyno on the same day:

these people seem to have no 'axe to grind' and I assume they did the tests the best they could,
but be aware it is very easy to 'cheat' on an air intake test on a dyno - just by very slightly aiming the dyno room's cooling fan differently you can affect the peak HP by 10.

You can also easily change the dyno result by not venting the exhaust from the vehicle properly or by allowing the tires to be hotter or colder between runs.

Note how well the stock Dodge intake does.
Do you really think that in the all-out 'V8 Horsepower Advertising Wars' between Chrysler, GM and Ford that engineers would leave some 'easy horsepower' by designing a poor intake?

 

i just put on a k/n on my 06 hemi , didnt notice anything but alot of noise , resonates in the cab pretty good at wot
