>pop the hood>remove plastic engine cover to reveal plastic valve cover and intake manny>wiring harness doesn't even have a protective loom
What, this stuff? Even my Twingo with its plastic airbox/engine cover, plastic intake manifold, and plastic valve cover has that.
plastic intake manifolds are superior because they cannot absorb or radiate as much heat as metal which means colder iats and more power. plastic timing covers also prevent heat transfer into the aircharge.anyone who believes otherwise is an uneducated moron who needs to go back to 8th grade science class
>>28985960Yes, because we all know manufacturers use plastic because of it’s thermal properties and not because it’s cheaper and fails at a predictable interval. Example: Ford’s 4.6L and 5.2L intakes that crack like crazy and cause leaks (turns out plastic doesn’t do well with hear cycles, which is what happens under a car’s hood).
>>28985951You can unironically blame Obama and the CAFE requirements for strict fuel economy and emission standards that have forced manufacturers to dump all their resources into building ticking time bomb engines with tech like direct injection, turbos, etc. It has forced them to cut corners and build things overseas. Trump is bring manufacturing back and reeling back these bad policies that everyone hates. I have hopes that manufacturers will start to revive old power plants that people have been yearning for, like the 12v Cummins AMC I6 which couldn't meet modern emission standards until the new admin rolled them back
>>28985993I'm hoping he just brought our gas prices back too
>>28985960>plastic goodpost nose
>>28985975>Yes, because we all know manufacturers use plastic because of it’s thermal properties and not because it’s cheaper and fails at a predictable interval.it's indeed more expensive to engineer and mold fiber-reinforced nylon than it is to cast metal, the plastic even has a higher strength-to-weight ratio than aluminum. Fiber-reinforced nylon withstands block temperatures of over 300 degrees F which no piston engine in the world would survive without failure.plastic parts don't crack, bad mechanics crack plastic parts. why should i accept an inferior, outdated automobile because some wrench monkey doesn't understand what in-lbs are?

>>28985975>ford makes shitty unreliable cars from poorly-engineered and defective parts that means all plastic parts are bad!!!!!!1111
>>28985993>Trump is bring manufacturing backAnd I have a bridge to sell you in Brooklyn if you think that's true
>>28985999>Fiber-reinforced nylon withstands block temperatures of over 300 degrees F!!!!!Wow 300* is a lot, what kind of temperatures can an aluminium intake manifold take?
>>28985960>plastic timing covers also prevent heat transfer into the aircharge.Wrenchlet
>>28986020stop insulting yourself anonjust read a bookfiber reinforced nylon parts are absolutely superior>they don't corrode>they help prevent heat soak>they are easily ported and modified with household tools and adhesivesthe downside is of course they're not pretty which is a skill issue and that garbage companies like ford and bmw make exceptionally shitty plastic parts on purpose so their cars fail on a predetermined schedule. mopar and chevy make plastic parts that last and only use them when absolutely necessary.>>28986019a better question is what kind of temperatures will an aluminum intake manifold ever see because if it melts at 500 degrees and your engine blows up at 280 then it's a bit pointlessly overengineered don't you think? why ae you paying for a manifold that will withstand jet exhaust on your nonturbo poverty spec shitbox?
>>28986023>mopar>make plastic parts that last
>>28986023Not trying to hear it wrenchlet kike, you can keep all that plastic shit
>>28985993Trump is litterally causing the world to switch to EVs. Gas cars are dead tech now.
>>28986029the pentastar oil cooler is actually based thoughbeit, it works perfectly fine unless you are a nigger.the funny shit is all the backwalk on this part when it came out that they never actually cracked at all, it was the silicone gaskets in between the the exchanger and plastic that were under-spec for the elevated coolant temperatures caused by EPA NOx regulations and melted. factory supplier error.people have even worse problems with the 3rd party metal ones because, being made of metal, they no longer actually work to exchange heat between coolant and oil, they just transfer all the heat back into the block because there is no insulation between the parts.
>>28986060>being made of metal, they no longer actually work to exchange heat between coolant and oil, they just transfer all the heat back into the block because there is no insulation between the parts.Dumass
>>28986062yes, you are. the plastic part has statistically lower iats and ect/eot
>>28986071You have never touched a wrench in your life.
>>28986072i have more wrenches than you have possible fathers you shit skinned porch monkey

>>28985975I've sold tons of those 4.6 manifolds back in the day
>>28986019>>28985999do you know the fatigue limit of this super-plastic? It must be incredible.
>>28985959its split loomto protect the wiresidiot.
I hate junk components but contrarianism about plastic is just reddit boomerism
>>28986074You have never touched a wrench in your life and you are a ricer..
>>28986001What game????
>>28986254>contrarianism about plastic is just reddit boomerismYour nose is showing
>>28985960either the plastic reduces intake air temps, or the air charge is moving too quickly to absorb any real amount of heat, coupled with the boundary layer of air further insulating the rest of the airgo figure...

>>28986274It's a parody of some Taiwanese game, chuds can't create anything by themselves
>>28986150Yes I know what it is and what it does, I'm saying even my mid-2000s tin can that was 100% built to a price has it. What modern car is so shit it doesn't even have something protecting the writing harness?
>>28986077>>28986054>>28986014The war is OVER, and oil prices are plummeting. Apologize.
>>28986458This is the second oil crisis in 5 years. So it doesn't matter, everyone is switching to EVs. It will take a month or longer before people even trust the war is over.
>>28986604The war is never over until total boomer death. Or Alternatively total Jewish death but we tried that already and it just ended up with us killing each other like 50 million Christians alone in Russia and somehow they tricked the boomers into caring about 20k jews that accidentally died in a camp. We gotta start with the boomers
>>28986458for aussies that just means the fuel excise is going to be put back in within a week or two, ideally asap, so prices will probably jump by 30c per litre from what they're at now. stock up
nylon glass plastics are superior to aluminum in non critical areas like intakes, oil pans, valve covers, etc. lighter, stronger (in the case of CF), just as resistant to chemicals and oil, and cheaper.This is a fact that boomers and bumpkins will die before ever accepting.
>>28987259
>>28987286Nobody believes you anymore Isreal. Even the boomer in chief is starting to get it
>>28986285>thing bad because umm.. the jews?
>>28987492You are a jew, that's why you want people to own nothing (plastic, it's nothing)
>>28987505>i hate something because it doesn't exist
>>28985999>over 300 degrees FThat's barely anything, the exhaust manifold is triple that easily, and they aren't making those plastic for a reason
>>28987518If your intake is as hot as your exhaust, something's gone pretty badly wrong.
>>28985993Every manufacturer could switch to hybrid at scale and beat Obama CAFE requirements. Blaming CAFE is a surface level argument. You'd be better served arguing CARB compliance for all those items. Physically fatter designs come from crumple safety requirements, no more trim looking vehicles. Trump adjusted Obama's CAFE target from 54mpg to 45mpg which isn't particularly helpful anyhow. The plastic parts are obviously cost cutting, whether to save money at scale or offset the EPA fine for every 0.1mpg off target you are. It's easy to blame emissions for efficiency and different technologies, but tech like EFI, performance hybrid, turbos, and direct injection are coming from race tech which isn't held to these requirements.
>>28987902this, the plastic parts are perfectly fine in normal operation.if you are a fucking nigger and never maintain your car, or have a truck/jeep let the engine get caked in mud and overheat then stick with the nigger-proof-metal parts.
>>28987972>The plastic parts are obviously cost cutting>costs more to engineer FRP parts>costs more to mold FRP parts>FRP costs 25x the price of aluminumshut up, retard
>>28985951This image sure brought out the chuds. Triggered much?My wife bought a rental return from Hurts and the only thing wrong with it was a missing oil filter door in the belly plastic, and the wrong oil drain plug gasket.At least they changed the oil.
