Hi, K and N cold air intake part # 50-1598 for 3.0L twin turbo RHO, I have herd good and bad things about it ,anybody have any info thanks
 
I've put a KN on every vehicle I've had. The RHO is gonna be the first I don't mess with the intake.
 
If you do it, go AFE or S&B. K&Ns don't filter well and let tons of crap through, take a look at some of the independent review videos of them. Basically just rock catchers. K&N is great with their marketing but thats about it.

I can't imagine there's anything to gain from an aftermarket intake on this vehicle. They already gave us one.
Absolutely agree!



As far as any aftermarket hi flow or cold air intake filters out there, the only advantage to buying one would really be the ability to wash and reuse.
With today's modern computer controlled engines, the only air entering the system is what the computer(or mapp) is asking for, no more or less.
If you want more air, then you going to need more fuel, plain and simple, That means a trip to the dyno for a computer adjustment
Even the temp of the air is questionable. Now back in the day of the naturally aspirated, non computer engines....you might have an argument.
IMO, the biggest Hi Performance con out there is the hi flow, cold air intake kit.
One things for sure K&N and all hi flow filters will let more dirt in.

Let me give you our experience. K&N released one for the TRX a while back ago. They prototype was done and they rushed into production. We pre ordered 10 units for inventory. After 5 months of waiting, we shipped our pre orders. Every single one had fitment issues at various installation points. We ended up returning every single unit and have them listed as out of stock on the site as I do not want to deal with the stress.

Now, did they fix the issues? Probably, so long story short, don't be the first lol.

Have a place on A1A in Lauderdale By The Sea, what do you recommend and can you get something Donald.

Recommend as in? We can get anything lol. If you are referring to an intake, I would wait but as others have said, you will not see much gains. Unless you are AFE who thinks their intakes make 50+ HP on all their kits (sarcasm)

All gasoline engines need a stoichiometric air fuel ratio. It’s just that some are better at achieving it than others due to modern computer control monitoring systems. As far as high flow air filters not all of them suck. Donaldson has always made very good air filtration systems. The cheap ones such as K&N are better at marketing than they are and actually making it worthy product. Having said that I fully agree. The factory airbox will be very hard to beat.

IdealRace will instrument the factory intake system and we'll report the pressure readings. Anything less than ambient pressure at the compressor inlet is a restriction and unnecessary increase in Pressure ratio the compressor has to deal with... reducing compressor efficiency. So rather than conjecture - we'll measure it. The factory air box may be adequate for factory power output, but I wouldn't be surprised that when we tune it - it generates a pressure drop in the system that can be improved.
