Engine radiator MISHIMOTO or OEM BMW

Mishimoto oem replacement is cheap dependable and lifetime warranty.

2004 E46 320i manual with 116k miles. Bought it just over a year ago for \u00a32000 probably spent around \u00a31000 on it (radiator, air con, rocker cover gasket, oil sensor, boot switch, coil pack), not too bad for a 20 year old car I don\u2019t think. Only thing that doesn\u2019t work on it is the cruise control, it used to but recently stopped.

I bought the mishimoto rad and it works well, the main benefit to the mishimoto is that they have a no questions asked lifetime guarantee. I had to replace it after a year due to a leak and mishimoto replaced it completely free with very good customer service. So the rads might not be as good as CSF but my dealings with the company have been very positive.

I went front mount on a DD that gets occasional track use. Huge benefit and reduction in heat soak. Needed to upgrade my radiator to a mishimoto 3 core to help keep temps down during track days. Overall happy with the upgrade, but not required until you start pushing big power.

Front tie bar, sometimes called a traction bar. Sharpens up the steering response, reduces torque steer significantly and in my case, reduced NVH

They're fine. They're one step above oem imo

I ran one for 6 years half of which being turbo. The mounts are known to fail so you want to make your own or keep an eye on them. Both sides failed on mine but Mishimoto’s customer service is top tier and they sent me a brand new unit (whole radiator NIB even though only mounts failed) no questions asked. The drain plug is also known to snap if you over tighten it. Again, they sent me a brand new unit when that happened.

I went through 4 mishitis in 2.5 years DO NOT each replacement cost $45 for “shipping.” I lost money and time dealing with recycled beer can BS.

You need to replace that. Bmws run hot. Only fix

I have one in my turbo VVT build. It’s big but seems inefficient, to the point that I suspect a properly designed crossflow radiator would shed much more heat by letting the coolant spend a proper amount of time in the radiator as opposed to this giant heat-sink top down tank. It’s on my list of things to replace.
