I was about to same the same thing.

If it can make 15whp, I think its totally worth $365 especially since it's PNP. Good Stuff!

someone body posted previously about the MAF tube diameter being only 65mm... if this bottleneck is deal with, power will be seen for sure without problem. I feel the rev-up will see the best gain vs the non-rev.

but then if the MAF tube is changed for a bigger one ,a tune will be required!
unless the ecu has enough fuel correction to deal with this.
I never tuned an 03-06 350z.

I have a 4" maf/intake on my Maxima and you definitely DO need to tune. Ecu can't adjust. Hell, some Maxima guys are running Land Rover MAFs (both 3" and 3.23" versions) and even minor AF tuning is needed just for those. Cheapest possible way to tune is with a V/SAFC. The actual maf sensor can't calculate the extra air for the ecu by itself.

(I'm tuning via UTEC - UpRev doesn't support '03 Maximas unfortunately)

Oh and 4" intake definitely makes power. Fine tuning my fuel before going for a dyno tune soon...would like to get an upgraded TB sorted out before then though.

Id be down. Didnt watch video bc im at work. This is ok for stock plenum? I see you may need a diff maf or porting wheres the truth?

wont fit the HR because they are twin TB and not the same as the 03-06

The_Assassin

Oh damn was thinking that we could buy 2 or something. But am pretty sure that if it sells well they will definitely make some for the hr

ive been running one of these for almost a year. no issues with idle air relearn. its a legit bolt on that compliments high rpm power well. imho you need a larger intake to take advantage of the larger throttle body, which is what i run.

The_Assassin

Oh thought it just came out. Any gains from it?

GTM sells a 3 inch Billet MAF housing for about 250 bucks. I bought it when they had a cycle for production, so that could eliminate the bottleneck the OEM housing produces. I'm excited about this product. Definitly buying.

i got one of surratt's harnesses and had a custom tb spacer made. mine wasnt tapered though. i actually bored and ported my old upper intake out until it was 75-76mm until the turn in the plenum. then i cleaned up the short turn radius on the neck.

I am working on 4 inch intake setup too and changing the MAF pipe diameter along with the rest of the intake is taking a ton of tweaking. I am having a hell of a time with it.

Do you have a thread on yours? I remember seeing posts in other threads that you're working on a 75mm TB.

Where did you get a 4" MAF housing and are you running a 4" intake tube? I'm running the GTM 3" MAF with the 3" COBB hose.

Nope, but same TB, same harness , just not using the adapter. I may even use the adapter.

Then I also have to order and build the 3.5 inch inlet tube with the built in MAF and jWT stack on the end

Oh never mind, found a 4" MAF housing.
