APR vs ECS Intake

**rtl5009** · 01-03-2016 05:30 PM

Got to see them side by side today, damn the APR tube from the box to the TB is much smaller. The APR is slightly quieter than the ECS too.

42 mm Watch for reference

APR:

ECS:

Not sure the bigger tube does anything... Air intake limited by scoop

The scoop? It doesn't work like that at all man.

Lol, you mean throttle body size?

the fuck

My point is that the bottleneck is still the intake scoop. Not sure anything bigger than the APR tube will net any gains. I personally think the APR tube looks more "natural" where as the odd shape of the ECS tube screams aftermarket

Is the the apr or the ecs making better noise? which one seems better build quality?

**GRUMPY-S4** · 01-03-2016 06:57 PM

ECS makes slightly more noise. Build quality are even... ECS probably a bit better

How is the build quality even if ECS is better.......

ECS carbon is a wider weave, more appealing to the eye IMHO. APR appeared to have the intake fully enclosed why ECS has a heat shield and a carbon fiber snorkel to direct the air.

I feel that the ECS intake gives the least resistance to the supercharger trying to suck air in, with the larger tube and open filter element. I have no data to support this.

Should have said "pretty even"

**GRUMPY-S4** · 01-03-2016 07:11 PM

Please keep the thread on Topic... APR vs ECS

**GRUMPY-S4** · 01-03-2016 07:12 PM

I agree that the ECS is more appealing to the eye. In terms of restriction and gains... Doubt any of these two are any different in power

**brianc21** · 01-03-2016 07:13 PM

I have ECS and have been very happy with it all around. Install, finish, sound, ect.

I do. I've logged and tested stock, the APR tube with AWE filter (stock air box), Roc-Euro, CTS, and ECS. The ECS definitely flows more air than the APR tube on the stock air box. The ECS, Roc-Euro, and CTS are all really close. I had slightly lower IAT's with the ECS, but it was close enough to call it a draw. Air flow was noticeably better with the ECS, CTS, and Roc-Euro (and again, all three were almost identical-in the case of ECS and CTS they were literally identical).

**GRUMPY-S4** · 01-03-2016 07:21 PM

Hence the more noise with the ECS vs the APR

**jongoslingS4** · 01-03-2016 07:26 PM

thanks guys very helpful answers

**GRUMPY-S4** · 01-03-2016 07:30 PM

And isnt the APR $700 vs $459 for the ECS?

All that, and never tested USP?

Just cause you had to be special and buy the Usp one doesn't give you the right to badger this man.

Go buy a real USP, one from Hk. :)

Haha. Nope. I have a friend with one, but he lives in a different state. Maybe I'll see if I can work something out with him next time I am up there. I try to do my testing in the same place/conditions which is pretty easy here (I have about 6 months of similar late night weather), but it's hard when other people/places are involved.

I forgot, I have also logged/tested the Eurocode too. It was about the same as the APR tube with AWE filter. I have not logged or tested the full APR, USP, Injen, or AWE at all.... Not sure if I'm missing any other common ones. Just as a general comment, I'd say anything that gets rid of the stock air box restrictions AND has a good/mostly sealed heat shield seems to be pretty decent (USP, although a bit ugly, fits the bill).

**jran76** · 01-03-2016 09:42 PM

This is very unscientific, but in terms of the amount of (S/C) sound: Stock is a 1, replacing the intake tube/stock filter bumps it up to a 3, ECS is a 7, and CTS/Roc-Euro is an 8. Or something like that....
