does this radiator come with rubber o rings like the oe/m radiator?

No. The o-rings in question are only available with the aftermarket Nissens radiator and those o-rings are for the quick disconnect couplings for the radiator hoses which are traditionally not available on their own.

Does this fit 2011 335i e93 with the n55? Please confirm. Thank you

Yes, this fits E93 335i's with an automatic transmission.

How much more coolant does this hold vs factory radiator?

This radiator does not significantly increase cooling system capacity. The main difference between this radiator and a factory or factory-style radiator is the significant increase in surface area (more efficient heat exchange) and a two-pass design allowing coolant to pass through the radiator twice.

What is the thickness of the core of this radiator?

1 5/8" (~41.2mm). An OE radiator core is about 32mm for comparison.

Does this fit rhd vehicles?

Yes. Left-hand drive and right-hand drive vehicles use the same radiators.

Will this have fitment issues with upgraded stock location inlets?

This p/n is designed to be a complete replacement to the stock radiator. Any additional modifications to the system may cause fitment issues.

does the BMW High Performance Aluminum Radiator - CSF 7046 have direct fit wit the stock hoses that have a pull clip and o-ring or do I need to get different hoses/flange adapter in. order to secure my hoses? Thanks

This is a direct fit radiator that utilizes the factory OE quick disconnects for the upper and lower radiator hoses as well as the bolt on lower fittings.

Is the CSF 7046 Radiator a direct fit for a 2008 BMW 335i (E93 Convertible) or is fabrication/modifications needed to install correctly? If modifications is needed, please advise customer of what to expect.

This is a direct fit for the years and models listed.

This will not fit a 2008 335xi with automatic transmission?

Yes. This fits 2008 335xi's with an automatic transmission.

Please confirm This will fit an 09 N54 Coupe with DCT transmission?

Yes. Our fitment guide does not list DCT fitment for the 2009 335i with DCT because that option was not offered in the United States until the 335is. But the same radiator is used for auto and DCT transmissions.
