Yeah, anyone with a very little post count who blasts K&N and posts a link to a different website I tend to raide a 'brow at.

 

LMAO well to let you know I'm 38, I've been working on cars for over 20 years ,dealer and private shop tech for many years, Factory trained tech, but hey, You can lead a horse to water , but you can't make him drink. You guy keep believing to claims of k&n ,flowcrapper and even the tornado. Let me know how that works for ya.

 

I'm gonna go ahead and give the troll a snack.

I'm sure most people here (at least me anyway) do not believe claims made by companies. There's been countless dyno tests by 3rd party researchers that prove cold air intakes do make a difference. While not huge they do make one.

Plus the members on here that keep track of there MPG and have installed a CAI see a difference in there MPG so unless all of them are miscalculating every time then I think theres an actual difference.

Thirdly if you knew anything about combustion engines you would know that cold air = better volumetric efficiency = more HP and MPG! Thats why turbo's work, they force cold air into the intake.

However a CAI does no good without a good heat shield to make sure that only cold air is entering the system and not warm air from the engine bay.

Thats a rather big snack isn't it I think I spoiled it's supper lol.

One more thing, why would you say to go with a WIX filter when it looks like the AC Delco filter did better on most tests in the link you provided. Anyway I mark this test invalid to our discussion because these were all tested on a diesel engine.

 

Well said Giod.

I do not believe the gains that any aftermarket company claims, but I do trust what others on here, who have paid out of their own pocket, installed, and tested, have said about certain things. On my Firebird I put on a CAI, and no, I didn't see the avertised 15HP gain, but I did see +12HP and a 1.5MPG increase in fuel economy. Still gonna tell me CAIs don't work?

I will agree with you on the Flowmaster muffler thing though. I've seen so many of them rust out in less than a year. They sound awesome, yes, but 3rd party dyno numbers on certain cars barely show a gain over stock. One guy had actually reported a slight loss.

Again, I go by trusted 3rd party sources and I also keep in mind that even the same engines react different to different things. You could throw a 2.5" catback on your Blazer, see a 10HP gain, and then I may put the exact same one on mine and only see 7.

 

Never said CIA's didn't give an increase in HP, but the filters let alot more dirt pass though plus, the gains are short lived, plus the oil from K&N filters tend to collect on the MAF wires and throw off reading to the ECM . Far as the test being on diesel why would that make a difference, do they use different air?

 

That's why I'm going to go with their Stainless if or when I do my exhaust...

I don't see that shield working all that great... Typical heat shields form an "area" that is secluded from the engine in an effort to keep the air cool... I don't see that happening with this one. If you want to see my setup just click on my signature for my Cardomain page.

 

The only people I've heard of having MAF oil issues with k&n air filters are the people who go oil crazy and over-oil the filter.

 

Or people that oil the filter, slap it back in the truck, and take off. You gotta let it dry a bit first...

 

Phil is right, even on K&N's website they address the MAF problems. The say that the only reason why the MAF has problems is when people get the refill kit and clean the filter they apply to much oil and it eats away at the MAF and its wires.
