For another 120 bucks they will sell ya the e-ram, too.....

Bling bling stuff, don't waste your time....

[Bones]

You're probably right I couldn't figure out how this is going to add horsepower as the stock filter flows plenty of air already and I wouldn't touch an oiled element filter

[Jim Sims]

Porsche didn't leave any easy/cheap horsepower gains on the table.

[widebody911]

As I found with my RS heater tubes. carbon fiber is a sure-fire way to add HP

[Axeman]

This is the cheapest HP increase for the money..we all know it!!!

[Joe Bob]

HEY,,,,AREN'T those FRAM filters?

[Wayne 962]

Bruce Anderson's dyno tests revealed that removing the air box filter had no effect on the engine's performance.

P.S. The cool collar works...

10 HP in the "Pretty" department.

[Todd Simpson]

I like how it says "up to" 10HP, then "more sportscar sound guaranteed" Why don't they guarantee the HP?

[jluetjen]

ooooooohhh! A "Track" version! That MUST be faster still! I bet you that they could increase sales further by adding the tag "Competition use only -- Not legal for use on a street vehicle".

[ChrisBennet]

It is a common misconception that K&N filters make the horsepower when it is the K&N sticker that makes the difference. Whadya bet Bruce and other testers didn't use the sticker?

I'll repeat what I posted on Rennlist:

I'd really like to see these manufacturers provide actual dyno results with their horsepower claims. It almost ought ot be a requirement. I mean, this is factual information, not something subjective. It's gone on for years, "Up to 10 hp!", etc. Then this "data" enters the vernacular of enthisiasts, and everyone starts to believe it. If you're selling a performance part for top dollar to Porsche owners, the cost of a dyno run would hardly break you, and if your claims are true it would provide credibility.

It's obvious that their scheme is to claim "up to", thereby sidestepping the facts, everyone seems to do it and everyone else seems to accept it. I suppose if you had an otherwise-modified engine that was capable of making a lot of horsepower, and you had one item holding it back (like a restrictive intake or exhaust system) then maybe you'd get "up to" the kind of horsepower gains they claim. But on an otherwise stock engine, I really doubt that you're going to get 10 HP from an airbox cover.

That being said, there's an element of coolness to some of these parts and that's worth something to some people. And some parts like the small cone K&N filters look racey and really improve accessability to the rest of the engine compartment for spark plug changes and valve adjustments, so there's some value there. No harm done as long as they don't actually reduce horsepower.

Case in point: I just spent $550 for a Dansk stainless sport muffler for my '88 Carrera. The claim was for "up to" 12 HP. The reality is NO WAY! My pants seat says 3-5 HP tops, barely noticeable. However the tailpipe looks wonderful, the part is exceptionally well-made, the sound is improved, and having it on the car identifies me as a performance enthusiast, so I'm already happy.
When I add the Fabspeed euro pre-muffler I may gain more horsepower than I would have with the stock muffler, so I expect to be even happier then.

So to answer your question, I think you might get a small horsepower increase from the part in question (but I doubt 10 HP), and maybe a little more if it's used in combination with other performance parts.

[RickM]

Actually a muffler change or modification on a Carrera can yield a 10hp gain or slightly more. However, I'm not familiar with the Dansk system.

I agree on most of the other crap that's out there.

[smarjoram]

Looks like the one I have already but with the end cut off.

Sportscar version looks like the one I have already with the lid off. Do you get the filter or do they just send you 2 short rubber bands? ; )

If we made manufacturers back up claims with independently conducted scientific testing, 90% of America would be out of business. Be realistic.

The Cool Collar may theoretically lower the oil temperature, Wayne, but let me share one of my many IT Corrolaries with you:

"In theory, theory is the same as reality."

[RickM]

Mark....I know a Mark Szabo for many years and we've been in IT for 20+ years. When I saw your name here I thought it was him....but quickly realized he was never a car fan.

We've got Consumer Reports and American Business seems to be doing fine (well, you could probably argue that too).

[KTL]

Leave the sleeping dog lie.

Meaning, leave the Cool Collar issue alone. The Cool Collar debate is the equivalent of an abortion debate!

[CarreraCat]

I have a 86 Carrera and I installed this airbox with a KN filter. There was a slight seat of the pants improvement but the sound improvement alone is worth it! The car sounds so much better when you nail it.
