Slim to nill. I bought two of these for my 1998 2.8l Audi A4 quattro since they were much cheaper than the OEM cats. I didn't notice any difference between these and the old ones.

The manufacturer says Yes to HP, no mention of torque in the answer. Although in a later answer on the same page, they mention lower airflow restriction is proven to increase HP and torque. http://www.knfilters.com/faq.htm#3

I have been installing air intake systems and exhaust systems to all of my vehicles for 20 plus years. The combination of the two does increase hp and torque as well as fuel mileage. The fuel mileage can only be realized if you keep your got out of the new hp. Lol. Yes this system does add hp. Simple to install s well. I hope this helps.

None, after running it for a while, what fealt like a gain was not, dyno showed same results a a drop in performance filter. Also mileage dropped, to 25 mpg from 29 mpg. I recently returned car back to stock, power is the same, fuel economy back up. Only positive thing about this unit is price, and sound. I had the Mopar unit, prior to this, and a K&N; as well, money wise, lesson learned just buy a K&N; replacement filter and save some time and money. On a side note if you are looking for bling and nice tone from engine, then the unit is worth it.

You get extra horse power maybe5-10 depends on setup but if your going from stock it's a must buy you hear and feel the difference.

I really am not sure of what the horsepower is but let me say I have a 300 foot driveway that is uphill and have at times had 2 feet of snow and it does a perfect job. I consider it one of the best purchases I have made. As a matter of fact I previously have had a Yard Machine and a Toro that didn't do the job and in fact broke down. I had to repair the yard machine twice aat a pretty high cost and the toro cost me 300.00 to repair. Now I only use the Toro to clear the back deck . The Yard machine I gave away because I was tired of it breaking down at the worse times possible.

I cant say i have seen an increase in hp it does soubd great though as for the install really easy driveway install the muffler clamps right into place no problem only thing is you are going to want to adjust the trumpet tips on the end mine were not even after install and thats easy as well just loosen the bolt adjust and tighten install is less than one hr no need to weld.

Not much horsepower gain. It adds a lot more audible boxer rumble to the exhaust. Low end torque is reduced slightly, but still worth swapping into your vehicle.

We have this vacuum, I can't advise on that, didn't know vacuums were rated for horsepower. Can say we like our vacuum very much and would recommend it.

Hi RichS&B; does not provide horse power specs. This cold air intake results in a 36% less restrictive improvement over the OEM air intake. Based on the less restrictive nature of the S&B; cold air intake you would probably see a 5 to 10 % increase in horsepower and torque. ThanksTruckCustomizers.com

On the economy setting expect 1-2 mpg gain. I run the tow setting and get the same fuel economy as stock with much more throttle response. Take into account I have an 07 3500, 5.9, 6 speed manual

Does not make a noticeable difference in noise but will help with MPG and some HP increase. I use K&N in all my vehicles:)

I have an '06 LJ with a 6 speed manual and 8" lift. I noticed a definite increase in power-maybe 10%. Gas mileage unfortunately stayed the same, even after exhaust and air intake tweaking.

Need tune and upgrades the intercooler only helps with heat soak so maybe a little hp gain not much

I have a 408windsor 425 hp. Had it cranked up to 4000 rpm. No worries no fears. Doesn't move with a quick pop on throttle either.

I cant say for sure but an educated guess would be yes due to the smaller motor expect about 2-3 more mpgs depending on how heavy your foot is. As far as HP goes I'm sure you will experience better throttle response.

None, but my tahoe runs much smoother now and it feels like it has more power.
