Blox Plenum Spacer

[phil4watching]

i have an 06 coupe. but this says -05.... would this still fit? looking to buy it tonight

[Sentientbydesign]

To my knowledge, the coupes have the same engines from 05-07.

Should fit without a problem.

[joe603]

Yes, it will fit 05-07 coupes and 05-06 sedans. However, you will not notice any increase in performance without the MREV2 lower plenum.

alright, thanks guys. i know it probably won't have much difference in mpg, but i'm looking for as much as possible because i have to drive 50 miles to class everyday... Joe- would it still help in mpg

[Sentientbydesign]

Synthetic fluids will probably show more effect than the blox spacer. You could also reset the ECU and throttle release and drive like a grandma

lol i was also planning on doing a CAI also..

JOe i have a question for you....Since i have a automatic do i need the mrev2 too?I have a 06 and every time i ask this question nobody will give me a straight answer

[phil4watching]

yes you do...only the 03-04 are blessed i believe

JOe i have a question for you....Since i have a automatic do i need the mrev2 too?I have a 06 and every time i ask this question nobody will give me a straight answer

Technically, no, but the MREV2 and the automatic lower plenum collector are slightly different. The MREV2 has is Ported and Polished for flow improvement.

Oh...wait...I'm not Joe.

[ryan_g35]

well he always is the one to bring that up.so thats why it was directed at him.. but since you know the answer im glad you helpped out

so should i just invested the money for the mrev?

[Sentientbydesign]

I would contact Tony over at Motordyne. Ask him what the true benefits of swapping out the lower collector on your G are going to yield.

Their site makes a bunch of claims for the REVUP engine. They don't say much about the non revup other than that you get a $100 core exchange.

Part of the issue with the plenums is that there are two grades. I was talking to Tony at Riverside Infiniti (different Tony) and he said that you can have two of the same part number but one will be very smooth and the other will be like sand paper. As such, the gains from moving to the MREV2 will likely be dependent on which you have.

[joe603]

This is a good question, but I'm going to have to agree with SBD. While Motordyne explicitly mentions that the REVUP engine will benefit from the MREV2 lower plenum, it doesn't specify the auto version.

Talk to the motordyne guys...
