Default intercooler is an intercooler?

Original plan was to npr intercooler the grey car because it's drop in and is a known good upgrade. But what makes these cheap $100 eBay intercoolers different from a treadstone or factory npr intercooler? Labor cost to make them or are there actual structural difference that make the eBay ones so much cheaper?

put a good core up against an ebay core and you'll know what's up

EBay core doesn't dissipate heat as well? Less fins or tubes?

here's the "face", ebay on left, Garrett on the right



this is the side view of the garrett


this is the side view of the ebay cooler


of course this is all relative to goals and needs. if you're not going to be making a lot of power, a la the average tbricker, the ebay stuff works fine.

be aware that many of the newer ebay intercoolers have less in the way of internal fins

A new npr isn't that expensive but I was not sure what made one more expensive than the other per say. I figured it was the quality of the core.

tube/fin vs bar/plate. npr is a good intercooler, esp from a drop in and go perspective. again, it's all relative to the time you want to invest and where you're trying to go. IMO the cost of time to fit the ebay intercooler probably offsets the savings, but that math may not be the same for other folks

Ebay intercooler is considered a huge upgrade over stock, yes? Do88 is likely better than ebay, yes?

Just a quick daily driver that fits together with minimal mods to make stuff fit hence the attraction to the npr.

This is the one? Brand new for 220 shipped or should I search ebay for a "real" npr?

The last CX Racing intercooler I bought off of eBay looked exactly the same inside as any aftermarket intercooler I've ever seen, and way better than factory crap. The fins weren't bashed in, welds were clean, and the price is great...

I'm a bit confused about those pics Linuxman, respect due, but pretty sure the first pic isn't a brand new intercooler lol.

Marvelous3, I'd go with the CX Racing route, for the price of an NPR you could get the piping and intercooler for the same price, all new stuff, and will support more than the power you are aiming at.

If you're confused it's because you're lacking mental acuity. Of course it's not a new intercooler, new intercoolers don't have leaves in them either in case you missed that one as well. I don't recall stating the ebay intercooler was new, but age doesn't shrink the core.

If you are not sure what you are looking at on the differences there you could stop and ask.


for another point of reference (not that it matters to any of you guys), we swapped cores on one of those joe blow 12x3x18 "generic" ebay intercoolers on a turbo honda, and picked up around 100whp, same size garret core.

The difference in the pictures are tube and fin vs bar and plate. Seeing it in pictures I can see why one is more expensive than the other.

The anecdotal story about the Honda is not an uncommon story. I've read that stuff in a bunch of places and now seeing them side by side I can see why you get a 20% increase. And for what, $200 extra? Seems to be a no brainer.

NPR core made for ambient IAT in the Hornetkar on the track. Do it.

IAT's before and after? Manifold pressure unchanged? Ignition timing unchanged?

it was first pull after it was installed. I don't really have much more data than that, it's been a while

Why would you post a pic of an intercooler you crushed into something? How is that relevant? Why try to insult me when you posted an obviously seriously damaged part as a comparison?

The CX racing intercooler is a great improvement over the stock intercooler. Can't really argue with that.

100 hp on a turbo Honda just from an intercooler swap. Ok then...it didn't ever have an intercooler so you added one and upped the boost a lot? I think there might be a bit more to the story than just an intercooler swap

100 hp is a 20% increase? That's a pretty serious Honda, lets see it! I love hp

If you don't understand the point of the pictures, you need go back to your play room, sit down, shut up, and color with your three old crayons. Stay inside the lines please. Ignore the goddamn dent, that had nothing to do with it.


I don't have an axe to grind against cheap ebay intercoolers, I've already said as much. but if people want to know (because this seems to come up on occasion) "Why would you spend XXXX on that intercooler when there's this cheap $3 intercooler on ebay?!!" that * might* be a reason.

I don't know... why would you buy a garrett turbo when there's $100 ebay turbos? PSI is PSI right? what does it matter?

I could probably go into more detail on the honda intercooler but if you haven't connected the very close dots yet based on the information already provided

I don't know that it would do any good. It was around 11 years ago, the car went from a well tuned ~500whp to an out of fuel pump 6xx whp on the first pull following the core swap (as in, cut the end tanks off and welded them to the new core, in case that wasn't obvious). They had to turn the boost down after the swap. So, you tell me, Why would anyone do that?!
