Who notices a difference with these 2 filters over stock?

 

Impossible to notice any difference by switching from a perfectly fine stock paper filter to a K&N. I'll wait for those that claim a noticeable difference though to chime on in....."10whp over here!"

My opinion is that the breathing is perfectly fine on the HR motors, just put on your choice of a catback, toss on some LTW wheels, and swap in the 4.08 FD to really open er up. Don't mod just for "mods sake" or cause everyone else is doing it, sometimes less most certainly is more...that is unless you're a "likes carbon fiber dash kits type."

 

I ordered mine because I want tokeep the stock airbox and have somethingthat will flow a tad better then oem and something i can clean often instead of replacing. I know it probably wont yield much gains but its more of a durability modfor me. However I will have the car redyno'd on the 12th withthe k&n.

 

I have them, I do notice a deeper sound from 1/2-open throttle.

 

Curious if you ever redyno'd?

 

Yea I'm gonna get them. I know they'll breath alot better. Maybe 2hp gain. Thats enough for me for 80 dollars or w.e it'll cost.. They'll last longer too. And I really wanna see if it'll change the sound. I hope it deepers it. But I can't see how air filters can do that.

 

I seriously doubt it will change the sound. Maybe if you removed the OEM airboxes and replaced them with conical air filters, then I can imagine a change in sound. But don't get your hopes up with a sound change from just a K&N air filter.

 

I have redyno'd. But it was a different shop so i really cannot say if the gains are real or not. However there was another HR there with similar mods except he had fujitas. He had like a 2-3hp more then me but I had a good amount of tq over his

heres my dyno slips

previous with AEM intakes, Fast Intentions exhaust




The msot recent dyno with K&N drop in's

 

Holy hell those numbers are nice. Wish you had been stock but oh well...Congrats!

 

when u redyno, u should buy a set of new clean stock filters and dyno it with both to see if there is any difference.

new filters are 27 bucks with tax for both at the local dealer

we can start a little paypal fund for u to buy the filters for testing purposes

i'm willing to pitch in 3 bucks, if we get 9 more, then the filters will be paid for

who else is willing?

Actually I have dynoed one other time after that last dyno. I dyno anytime if there are opportunites for cheap dynos Last dyno I paid $40 for 3 pulls with a/f.
I have clean stock filters. I just dont see the need for a comparison over stock. I think its not a great difference but what is great is that you dont lose power like other intakes.

If the greddy kit gets held back past the summer I plan on putting headers on the car next month! so stay tuned to that!

 

hmmm great thread

 

there are headers for the hr? i mean something other than that ebay crap

 

Well after speakin wtihsome locals. There has been people here that haev put headers on their HR.

From the looks of it the older headers do fit the HR. The bolt pattern and spacing is plenty. Only thing now is you have to switch out the the pre-HR cats or test pipes

I wish I knew this before I bought my FI test pipes.

Next up headers and new test pipes for me than dyno

 

Switch out to pre-hr cats/testpipes? Sorry could you clarify?

 

so they can bolt on to pre-hr headres.... headers and the cats are the only difference in the exhaust system

 

so 06 and below headers will work on our cars?

 

yup pre HR headers will bolt up to the manifold. By using pre HR headers you would also need to use the pre HR test pipes, high flow, or cats.

 

Wish I knew this before my HFCs.. lol. Good information though man. Someone update the sticky up top

 

The pre-HR headers is interesting. What headers are you guys going to use?

Oh and do you guys think HR designed headers would offer better gains, or is it just about fitment?
