Intake Recommendation?

[dh58]

I had the AFE cold air intake and I liked it however it's pretty expensive (~500USD). Does anyone know of any comparisons or indepth reviews?

On stock turbos there is bugger all if any difference from the stock airbox.

If you come across a second hand one maybe but don't rush out and get one.

You will see no difference in power.

Is this an opinion or tested? If its tested can you link me? Thanks!

Tested on my car on the dyno at advan absolutely no power gain.

If you come across a second hand one go and buy it but don't waste your money on a new one.

Thanks!

Get a Mr 5 intake and be done with it. One of the few I believe that shows benefits.

[martymil]

Not on stock turbos, the factory airbox is perfectly suited as the factory inlets restrict the flow not the filter.

When I get my inlets I want to go back to stock airbox and will be testing this against the afe dual cone intake.

I had mr5 and ditched it in favour of the dual cones no power difference what so ever.

Lots more noise with the AFE DCI's, didnt notice much more power tbh

[martymil]

I went from stock to mr5 the dyno curves where identical and I said stuff this and went dual cone afe and was exactly the same again.

I will be having a big sale of performance parts very soon just waiting for my nephew to bring some parts back from the U.S on Wednesday for me.

Never know the dual cone might be up for sale.

I have a burger tuning intake... Dyno showed a total of 2 HP gain.. but it sounds great

[yawn]

Hmm stock is the way to go then unless you want more sound?

[dh58]

Yes but what about temps etc? While the HP might not be there, the point is cooling?

Also why are we upgrading the inlets to have a restrictive air supply?

[BMWhoarder]

Temperature plays almost no part prior to the turbo. You could have a 5 degree difference in intake temp (unlikely. remember the intakes route around a hot engine/engine bay to get to the turbos), that once compressed by the turbo, becomes identical.

Focus on decreasing temps post turbo with an effective IC, meth and e85.

[dh58]

Thanks ba114.. Good info.

I don't want to do meth.. and not e85 (yet). I don't have a reliable supply of e85 because of where i work and travel.

[BMWhoarder]

if we had NA cars, intake temps would play slightly more of a part.
Given how turbos work, and the related heat introduced as a result, either stick with stock, or go a cheap DCI solution. Throwing hundreds of dollars at it is money wasted that could have been better spent of actual performance increasing mods.

BMS DCIs were USD95 from what I remember (3 or 4 years ago now...). Given they are short rams, your IATs would be quite a bit higher compared to the stock airbox.

But you can fix that with a bigger FMIC and....methanol injection. Worked for me.
