Very nice write up, thanks!!!

I know the Stillen G3 makes the most power, but I'm still kinda thinking that is more due to the larger MAF tube leaning out the AFR's than an actual flow rate increase. I'd like to measure the ID diameter of the MAF tube on the original stillen intakes that didn't make much power. I bet the G3's are slightly larger.

I'd also imagine you can get nearly identical results with drop in's and a larger MAF tube.

Which intake?
 

hey all,

just wondering what the go is with our Australian laws regarding a CAI setup? and which ones we are able to use over here... i was thinking of the next 3..

- hks
- stillen
- injen

however with the hks are these going to be ok if police look under the bonnet, as i think they are oil based and do not think thats lega?, and i heard that paper based filters are ok?:confused:

any help would be great

cheers guys

Think all exposed intakes are not ok, that's why their all covered in stock cars

Which intake is best for me?
 

Hey guys! I don't know much about cars and what not so I need a little advice.

I had an intake on a Mustang a few years back, but I got it off eBay so it probably wasn't all that good. I've seen a few threads on here about short ram or long tubes. From what I've gathered, short ram is mostly just noise that will reduce performance and the long tubes will give you better performance, but you may have to cut things under the hood.

What I'd like to know is a couple things:

1) If I spend money on an intake, I'd like to get a good one that will increase my performance, but also not decrease my MPG. Is this possible?

2) Are there any intakes besides the short rams where I wouldn't need to cut anything under the hood to make it fit correctly?

3) Will I need a tune? I don't plan on racing...just really looking for a bit more power and to help the engine in the long run; so I don't plan on getting a tune. Without a tune, will the car start throwing codes or anything?

I apologize for all the questions, but would really appreciate any advice.

Thanks!:tup:

I'll answer your questions before people start trying to kill you for not searching because they are pretty straight forward.

1. I'm not sure any intakes decrease MPG. It might seem like it because once people have them installed they like to redline their cars 90% of the time. Better air flow should = better MPG

2. With the Stillen G3 intakes you just need to enlarge holes on both sides. Injen intakes you don't have to cut anything, but you will need to replace your windshield washer fluid tank. Either way, you'll be doing some sort of modifying.

3. If your just doing intakes for now, you do not need a tune. Just disconnect your battery after install and let the ECU reset and it will adapt to the added airflow. You won't throw any codes as long as your MAF sensor is hooked back correctly and there are no leaks

Thank you! I saw the Injen intake where you had to modify the washer fluid. What about the AEM intake? It looks like it comes with a new container?

BTW, if the intake increases the sampling tube of the MAF it will run leaner. The ECU cannot compensate for that as the air measured via the MAF is not the same.

I think with the Injen they supply a smaller one and you just replace the oem one with the new one. Only down side being you might refill your washer fluid container more often. Also some have said they think that with the Injen they can reach the filters to remove them for cleaning without then need to remove the entire front bumper. It may be possible to get to them through the wheel wells. The Stillen Gen3 will require bumper removal.

I can't comment on the AEM.

It seems like the Injen would be my best bet. I definitely don't want to run leaner. I really don't want anything to change from stock...just better air flow I guess.

If you're worried about running lean you can always just get a tune. Not that big of a deal.

I would prefer to not get a tune. Looking for more "plug and play."

Yea, what about a plug and play tune? lol

But if that's the case I personally would leave the stock intakes alone(or if anything put drop ins) and then change the exhaust and cats.
