Ruey, we're talking about a vehicle air filter, not the tire, fuel system, tranny or motor; just a darn air filter. How many times has there been a air filter sabotage by anyone, including vehicle owners? None that I know of. You really think that a valet would cause your air filter to ...well, whatever, you're scrambling here man. Like I said earlier, I have driven on these and they last a very long time and I don't argue the 1million miles claim.
Where in the world do you drive? Indy 500? So you spend $50+ just for a 0.001 off the line response. I wonder how much fuel you burn in the process. For starters, for a SUV, the HP vs RPM curve for the K&N is useless until far up in the RPM range. You'll still get miserably slammed by a stock ML55 while your'e messing up your MAF. It really just isn't not worth the pain for a ML if your goal is performance. |
as i stated in the previous post i never said that the filter adds hp's. my previous post was touching on two points.
1) Throttle response is not always benchmarked by hp gains. You can have more hp's but poor throttle response as you know it is useful since you seem to be into performance cars for over 200k miles driving experience and doing some creative driving techniques like heel and toe a good throttle response helps alot more than hp's etc.
2) In my effort to keep thing short and not spend much time writing my post, I didn't make myself clear and was thinking about another subject. I was referring to longevity of the engine is all relative to the engine itself, and unless you put the exactly same cars side by side that went through the same elements, you can't blame the filter for shorter engine life as others have suggested.
So my closing remarks is that it depends on what you're trying to achieve in whether the K&N is or is not for you.
