WTF is an Intake
modulator? Sounds like the butterfly on the factory Intake
Having a reserve chamber in your Intake
tube (like the V2 Intakes
, large chamber with smaller elbot to TB) can help performance a bit by offering a buffer of air, for when you mash the accelerator, that reserve of air rushes down your TB, and it isn't choked by the demand for fresh air (normal Intakes
, your bottleneck is the filter istelf in this scenario). However, it's only benificial with a performance exhaust installed, and I doubt seriously that it'd give you an extra 20 HP.
Just go with a decent Cold Air Intake
, I suggest the Injen
or AEM Intakes
. The filter should be low restriction, funnel-ram type (think aikimoto) I prefer a stainless element to the oiled cotton or foam types.
As for Myself, I've finally selected my Intake
setup, I will be going with a true-flow Intake
system for my GTS. It replaces the factory tubing and MAF housing with Mandrel bent aluminum tubing, which goes to the factory airbox. the filter is replaced with a high-flow panel (like the TRD
filter). this way, the Intake
will flow much better, It will meet the demands at lift, and it retains the stock airbox and butterfly, so not only should the temps stay down, but the low-rev loss of torque associated with butterfly removal will not be an issue. add to this the fact that you won't hydrolock the motor, and no CEL coming on, and it's a no-brainer for me. Once I have the exhaust installed, this should make a noticable difference.
