Hello Infiniti fans out there I wanted to know can I fit an M45X engine dual intake(09-10)nto the M35 , I have an 08 M35X ,5 speed auto,that came with the single intake that recently siezed..I know the M45 suffers from oil consumption and what should I expect to pay in terms of purchase and labor,I know different places and mechanics charge different and what reputable website can you recommend to purchase from..
And from folks out here that have done the engine swap what problems have you encountered long term after doing the swap..any helpful simple advice would be greatly appreciated

It's not as simple as just swapping the engine, you also need to take care of the harness and ECU, etc.

Is there an M45 engine with dual intakes? I didnt know that there was. I know the 35 went to a dual intake model but I had thought the 45 engine remained as it was its whole life until the switch to the M56 engine with dual intakes.

Anything after August 08 I believe is considered next yrs model so yes the M45 S and X model came with dual intakes just like the VQ35 engine but the X models stayed 5 speed until they transitioned to the 3.7,5.6 engine

That is not correct. Enigma is right, the M45 never went dual intakes, only the M35 did from 08-10.

And you are wrong search for 09-10 M45 model had 2 air filters...you not gonna find many for sale thus the 08 models with the single air intake

IDK, looking online I see the air filter for a 2009 M45 as a single filter piece. That is looking up at both Napa Auto Parts and Infiniti Parts USA. Looking at aftermarket, Injen intakes sells a M45 intake kit that is compatible with 2006-2010 and is just a single intake tube.
You can also look up the intake housing that holds the filter on Infiniti Parts USA and it says the 2009 M45 requires 1 housing.

I guess then probably the ones I saw might have had like an engine swap or modifications but nothing about them looked aftermarket
