The throttle body spacers don't seem to do much for performance and some of them cause an annoying "whistle" noise. A lot of people, especially those at the Frontier and Xterra forums, have installed the XTP spacer and raved about them. There are dyno charts to show the before and after affects of the spacer and they do seem to smooth out the power and torque curves compared to stock and give it a modest increase in power and torque.disallow wrote:do you mean an intake spacer?
I've always thought these were snake oil, but then I saw that SMJ was thinking about putting one on so now its got me thinking...

The problem with your putting the filter in the stock box at an angle is two-fold. First, you are adding a 90 bend, which adds restriction. The second is that the cone filter is not positioned in the most optimal direction.ValleyWalker wrote:I just added a pic to my above post.... what are you're thoughts on that?
Anyway, I've reached out to the seller and told him it's not working.
I'll see what he says when he gets back to me but I'll return it and go w/ a full K&N setup
The K&N drop-in filters only produce about a 2 HP gain and is not really worth the expense, IMO. It's probably why K&N never show any dyno results from the drop-in filters.SETI20 wrote:Seriously. Just go with those flat K&N replacement filters in the stock box. And if you're feeling particularly DIY like, you may replace the plastic piping to the intake with some of those cheap aluminum tubing kits. Spray with rhino liner to make them nice and stealthy. Smooth tubes > ridged tubes.
I recall reviewing a study on airflow K&N Filter Charger drop in vs OEM Paper.smj999smj wrote:The K&N drop-in filters only produce about a 2 HP gain and is not really worth the expense, IMO. It's probably why K&N never show any dyno results from the drop-in filters.
