K&N drop-in intakes?!?!?!? plus an exhaust is 300whp? Holy moly. No other mods? Isn't that kindda high. I wonder what gains I have right now by just adding an exhaust, with no other mods. Did I gain like 15whp? (no access to a dyno in my small timbuktu town )

As far as K&N drop-ins... aside from the worry about fouling the MAF sensor (I am still on the fence regarding this... seen both sides of story), what I am worried about are more the particulates that get in. I mean this from the standpoint that I noticed on my G35, that since I switched to K&N, my oil was a lot darker than pre-K&N. Not sure if there's any truth to that at all... but I also read around that some folks did notice that too. Now what that means.... I would be led to believe that the engine is simply running dirtier... maybe someone else can enlighten me on that topic.

Yes, I am thinking about getting HFC's instead of getting a CAI. So if I have a CBE and HFC's, is a tune needed? I would like to NOT get a tune... don't want to void the warranty just yet. Maybe in a couple of years

He was spamming other threads with complete gibberish, I don't see how does "o2 airflow can cesspool" sounds normal or makes sense as can be said about the rest of the post. FYI, a cesspool is a large pit to dispose sewage or refuse.

i personally dont think 300whp is high but i have the k&n short ram intakes and borla exhaust. it did get a ecu tune.
our z's make 276whp stock, so my numbers are relatively average

The oil color after several cycles can very depending on the type of oil you use. The darkening happens when the oil absorbs carbon deposits from detonation. I could be wrong, but I'm assuming low grade gasoline would have this effect. The K&N filters out the same amount of particles as paper filters if oiled correctly. The oil is there to compensate for the larger openings. I have about 6k miles with my K&N's without any problems. I honestly don't know of anyone having the MAF sensor issue aside from unreliable sources.K&N Mass Air Flow Sensor Statement

Makes sense now. What does an individual gain from spamming like that? It's not like he's selling anything... weird... and sad, at the same time.

That makes sense. I've seen some stock Z's though, lay down 260 or less. Just a diff't dyno maybe? Either, yeah those are some great whp numbers man. Keep it up.

Yeah, like I said, whether it's hearsay or not, not sure which is true. Not saying anything was wrong with my K&N filter... I never oiled it... had it on the G for 1-1/2 years, then I traded her in. But I remember before I changed to K&N, when I changed the oil, it was mostly "newer" looking. It's been on Mobil 1 since day one of ownership, with an OEM air filter. Then switched to K&N, then oil started getting darker every change. Like I said weird.... I didn't experience ANY problems whatsoever, and I did notice more giddyup from the butt dyno. I just found it odd that my oil started getting darker. G was stock other than air filter.

Im not a mechanic but my only explanation about that since you change your filters to K&N you actually increased the airflow therefore an increase in air flow = increase in combustion in the chambers equates to generating more HP and more heat inside the engine causes the oil to burn faster thus its more darker.

More air + right amount of fuel injected = More Combustion= Inc HP = more fuel efficiency.

But nothing wrong with that in fact my mechanic told me it just means your car is running more efficiently when your oil becomes darker in time for your scheduled oil change.

To me it made sense.

Default Question about this exhaust

I am thinking of getting something similar that has been mentioned. I am wondering about getting k&n cai, invidia gemini cbe, unorthodox or stillen pulleys, and I am undecided on which HFCs to get. I want more power but without making my exhaust raspy or having a lot of noise in the cabin. Any recommendations??? Any feedback is much appreciated, thanks.

I do have a Z1 HFC so far no rasp but to get out of the noise inside the cabin is quite impossible because as you free up your exhaust it does makes a lot of noise. But you will love it for sure. In fact I come to a point where I feel its to quiet for me now.
Thinking of getting a test pipe in the future. The Ark HFC is a nice recommendation but I find it to expensive. Berk HFC is another option comparable to Z1.

What is the difference between the Z1, berk, and invidia hfc?
