dont "think" you can just remove...
but i would suggest using one from a lexus. "maby some turbo users here can tell you what series to remove it from" its suposed to be around 25% more air.
or the maft pro.
but you will need the larger 550cc injectors aswell to add 25% more fuel. (i believe the 7mgte comes with 440cc)
also you could have just easliy searched this.
