its stock style, but its built worse than factory. its aluminum core and plastic outside. not metal outside. the plastic will eventually get stiff and brittle and break. then its time for a new POS radiator. how long? i dunno 2 years? my moms car just broke a piece in the heating system within the heater hose. it got brittle, cracked and was leaking, then when i picked it up to look at it, as my mom was overheated on the side of the road with my 2 78 year old grandparents, it cracked in my hand and shattered. They waited there an hour as i had to go to the autoparts store to get a part. then fix it where they were armed only with a knife blade as tooling. It worked out, but it was all due to a shitty plastic part in the heating and cooling system.
I wouldnt risk it. Get a good metal replacement ALL aluminum. Those are the best.
