Leading evidence: 'over-oiling' (1 discussions report identifying this cause; no attributable repair resolution). Across 1 matching discussions, the most frequently mentioned possible cause is 'over-oiling' (1 discussions; 1 report identifying it and 0 suggest it). The most frequently discussed action is 'Check anyway, i'm going' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.

For $75 (used) I paid for the device it is pretty neat.

I have the G-tech Pro thing I used on my Acura to see the effects of the mods.

Since I'm due for my smog check anyway, I'm going to get smogged first...that way I won't need the sticker for 2 years.

Please do check the Durametric data as well as dyno, please.
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Since (to the best of my knowledge) this is the only intake that actually
guarantees
an increase in HP, I decided to pick one up. It's a good-looking piece of kit, which doesn't hurt.
The following stock pics show the intake and how it looks installed. I'll do some work with the IR thermometer after install to see how hot the shielding gets and determine if adding insulation would be useful.
K&N sample photo (I'll post mine once I get it installed)
Please note that (a) I'm familiar with MAF fouling, (b) I'm familiar with the known and alleged pitfalls of various intakes, including this one. If you're interested in following this thread to see how I like it and whether there really IS a demonstrable increase in HP (I'll do before and after pulls), please feel free to follow/comment. If you just want to yap about MAF oiling, how intakes are stupid, and/or how Porsche would have included a spiffier intake if it actually mattered because Porsche engineers are effing faultless and every Porsche is perfect when it leaves the factory, please go take your dump in a different thread.
Claimed HP gain is 23.8 HP. I'm not laboring under the misconception that I'll really see an 8% HP bump, but it would be awesome to get, say, 10HP. We'll see. Install coming on July 5 or 6.
Since I'm due for my smog check anyway, I'm going to get smogged first...that way I won't need the sticker for 2 years. Thanks for the reminder, though - I'd hate to give the smog ***** a reason.
Yea, I have a friend who failed the visual with his Ingen intake (non Porsche) and all the tech needed was the freaking sticker. Friend called Ingen the next day and got the sticker mailed to him. Put the sticker on and passed the test.
Do yourself a favor and put a scanner or durametric on it to read the MAF values before and after. One of the cheaper ways to know if your engine really needed the extra air or not.
If you're measuring and want to isolate specific mods, a digital manometer is the way to go but often expensive and a more involved setup process.
Or you can just get a before and after dyno.
I'll tinker with my Durametric, but I'll do the pulls as well. I'm not good with "it sounds awesome, so it's worth living in denial about my car actually now being slower..."
I had surging issues particularly at 65-75 mph constant hw speed with cone type intakes(fabspeed) on my old 996. Sounds great at full song but didn't notice much seat of the pants power. Mike
I want the dyno results. I have the G-tech Pro thing I used on my Acura to see the effects of the mods. For $75 (used) I paid for the device it is pretty neat. Calibration and correct installation are really important for accuracy of the results. If you don't position it correctly or don't calibrate the revs right...it goes nuts. On my first run in stock form without adjusting the G-tech, my Acura had 360 HP and did 0-60 in 5 seconds flat.
I had the K&N intake on my previous 996, 2000 cabrio, it was already on the car when i got it so cant comment on before and after performance increase, however i can tell you that it sounds SWEEEET!! at WOT.
subscribing. have one in a box in the garage, it came on my car, but i pulled it and put back the stock one. found it a bit loud, and i don't track anyway. very curious to see actual numbers and durametric results.
Your results will be interesting but not necessarily applicable to others due to the other mods you appear to have that potentially affect output as well. I also note that the K+N chart posted is for the 3.6, I believe you have the 3.4, do they have a chart for that as well? Not ******* on your plan at all, just pointing out differences. Your baseline dyno pull will be interesting to compare to K+N's baseline.
I'm guessing it will be next to nothing on the dyno. I have the EVO and didn't notice anything. The only reason I bought it was the previous owner broke the factory airbox mount nub and it wouldn't stay in place. IMO, they only belong or FI.
Wow, how obvious & simple, but I never thought of it. If at the same RPM, the MAF shows the same airflow, then its doing nothing. If there's more, then there has to be more HP at that spin. I also look forward to the results.
A warning about the KN. One the oil on the cone filter will kill your MAF sensor. Get the dry filter with the mesh. Also I had the unit on my car for a week and took it off. The car off the line will suck in hot air and it killed the performance off the line. Then on the highway it would work great and sound great. So to me it wasn't worth it. It did sound great but not much HP gain. I have a 3.8 upgrade when the IMS went. Got new pistons and sleeves from LM engineering. I ended up getting the 3.8 Stock 997 air box. Looks and sounds great.

The issue is over-oiling. Most people don't read the instructions and saturate the filter. K&N makes a spray now to eliminate some of the issue with improper oiling.
The oiling wasn't my issue it was more of the sucking in of hot air while in traffic and at a light. Car was a slug. On the highway it was great. Seeing your in California, traffic central, lol, you'll have the same problem. The oiling problem didn't happen to me. I removed the intake very quickly. Since my motor blew from the IMS issue, it was sent out to LN engineering and got 3.8 sleeves and pistons, I ended up putting the 997 3.8 air box. I like it.
Robert
5CHN3LL, Where did you get your filter? I probably could of saved you some money.
If anybody else want's to buy K&N 57-7000 I have the filter
