Description: 2002-2006 Nissan Altima 2.5L Exhaust Manifold Racing Header Stainless Steel
Part Number: 102233
Price: $135.74 (Shipped)

Important Note:

  • These show 2.5L vs 3.5L. Josh confirmed they are for the 3.5L and he installed on his Maxima. He is local to them.
  • As you’re aware these require modification of y-pipe for perfect fitment. Please research it. This has always been known with the Altima VQ35DE headers. They are NOT plug-n-play. But for the price, they are very well worth it. These also come with a downpipe so it makes an even more awesome price.
  • A few maxima members have already ordered and confirmed this is a legit shop. They’ve received their ordered with no issues.

Well I got my AEM FIC running finally after a week of messing with it, and it does run a 4gen maxima and the timing works on it too. Neat little set-up and a good option vs eManage.

I’m running it on my 1996 maxima with a z32 MAF, 410cc injectors and a t3/t4 custom turbo setup.. and I have a 2008 3.5l in there out of a 2008 maxima.. with a pathfinder tb.

Well it’s not much of a how-to really, and it’s not much of an upgrade either.

But nonetheless, a Reman from AZ done by the same company is $160 for a ’96 I30 (125 amp stock w/125 and 110 amp options, 110 = $130’ish IIRC) vs $210 for a ’04 I35 (110amp stock w/no 125 amp aftmrkt option listed)

I30/GLE = $160 125amp
5.5 Gen = $210 110amp

There’s really nothing to it. the pulleys all line up the same and everything, you just need to use a hammer to tap the bushing until it lines up with the location of the 5.5 gen one. If you lay them both on the table with the pulley facing down, you will see that they are nearly identical and what needs to be changed.

Hold the aluminum casing nearest the bushing between the edge of the table and your stomach, than tap, you don’t want to be tapping the bushing on that mount while resting the alternator on the pulley, you could snap the case or do damage to the alty, this will all become apparent and if you can handle replacing your alternator you are smart enough that this will be common-sense to you.
