325 N53 Mods

Hi all,

I have an E92 325i (N53) and wondering what mod options are out there from a performance perspective?

I have AMD in Lakeside mapping so power up to 265 and 320 (BHP & Torque respectively), also getting a K&N Performance Air Filter and RPI Air Scoops for a little bit more.

I've heard that the 330 intake is different to the 325 but not sure it'd make much more power on AMD's map?? Suggestions?

Also interested in a 335 style performance exhaust but no idea where to start. Anyone have any ideas?

Any other options would be greatly appreciated!!

TIA

I think you've covered all the bases. I doubt you'll get a big increase with just a remap (though others on here disagree). The main route for more power is to fit the 330i inlet manifold and then get a remap with 330i software. Other than that, it's a naturally aspirated motor that was pretty efficient from the factory, so you won't wring a huge amount extra out of it without the new manifold.

On the P/E, you can only fit a 335i exhaust if you renew the rear bumper for a dual outlet version. You can get a P/E for the 325i (I have one - best mod I ever did). Though I have heard suggestions that BMW no longer list it, so you may have to wait for a secondhand one to appear...
