Order the Rev Motoring silicone tube and forget the plug in the resonator, or even using that factory accordion tube. Swapping to the silicone tube has been demonstrated on dyno to actually gain HP.

The DIY Dinan style ram intake is worthwhile.

Don’t forget Charcoal Delete also!

Just buy a K&N (or brand of choice) Drop In and use the sealed factory box. You want cold air not warm engine bay air, and the ram mod supplementing stock snorkels will give you all you need.

I did a bunch of CFM comparisons and the K&N Drop In flows plenty of air for your set up. I did what I believe is the fastest 1/4 mile pass ever (13.9 ) on a N/A N52 with a K&N Drop In, Charcoal Delete, and Rev Silicone.* That intake set up can be done with DIY ram for around $100-$125 and will be all the intake you or any N/A N52 will ever need.

*(Plus other mods but just saying.)
