What kit is the best, Dual Side, Dual Rear, Single?

What K&N Kit has given the best balance of performance and gas mileage improvement for the street? Thanks.

 

i beleave the single in single out shows the best hp trq numbers

 

Feeling is one thing, but does anyone know the facts or has experience with theirs first hand? Thanks

 

Yes, Mike Troyer.

 

Sounds like a winner!. I was wondering if the Dual exhaust was better, according to this write up the single sounds great.

 

duals look better though!

 

I agree with you on that, I like that angled cut of the exhaust tip

 

What is the difference between an K&N Aircharger and an FIPK Kit?

What is your preference?

 

duals will have the most performance gain and the best intakes with the most gains are the ones which use an airbox. the company Volant makes the best...

 

Jon,
The Aircharger is the full intake kit for your application. They call the older applications FIPKs; the function is the same. I suggest dual exhaust, only, if you prefer reduced low-end torque.

 

I have 98 4.6 f150 with a flowmaster 40series delta flow(3inch in dual 2-1/2 outs into the magnaflow dual mandrel bent pipes and some 3 inch tips at the end. It sound real good

Also it only cost like 120 for the mandrel bent pipes and 69 for the muffler
