This mod isn't ghettofying the car. This is to be considered as a stepping stone for later mods. Most who did the mod has gained from it enough to actualy be movated twards purchasing a cai to see if it's that much better. Most of the mods need to be done if you install a cai anyways. I can't get either sites for the actual mod cause the other forums search feature is usless and my bookmarks are on my comp in Va. so here goes.
*I took a flat head to the tabs and pulled up on the restrictor plate.
*Removed resonator.
*Disconected vad lines but left flapper attached
*Purchased the reusable K&N filter(don't need this)
Restrictor plate soes as it sounds so it was removed. Resonator is designed as it sounds and it's removed. Vad is a flap that stays closed tilll vvt whn it opens. but untill VVT happens the air box is only 30%-40% efficent so it was disconected. Scuba is abother thing to be removed but since it's located behind the radiator it's removal isn't the greatest Idea so it stays.
As for the SRI idea on a mazda 6...I'd stay away from it. From personal experiences or downfalls I can tell you the gains you want are not gona be given with the intake. You are sucking in 180-210 degree heat from the engine and cooling fans kiling a few stock ponies. You may feel a nice gain in the morining as you drive off on a cold engine but second you get the engine warmed the sri does a 180 degree turn for the worse. you loose low end acceleration and vvt is just horrible. If you think I'm done....wait theres more

Try climbing a hill in the summer with a sri on and you will find yourself going "WHY is my foot to the floor but the car won't go faster than 34MPH!?!"
In short for for those who may have skimmed thru my post as usual...
*Airbox mod is considered a stepping stone.
*Flathead to lossen the tabs and pull up on restrictor plate(tray).
and
*SRI is bad for your Mazda 6
