Idaho-based aftermarket parts company Halltech Systems has released its new Hornet 518 cold-air intake system for the C8 Corvette Stingray.
This cold air intake system for the C8 Corvette Stingray replaces the factory intake and requires no additional modifications to install, nor does it require an engine remap/tune to see a performance benefit, which is good, seeing as it isn’t possible to apply a remap to the C8 Corvette at this time. The intake features a filter box made from polyethylene and a large Blue-Bee dry nano filter. Halltech says the intake allows for the stock connector hose, PCV fittings and left and right inlet ducts to be used, along with the OEM mounting bolts.
With this intake installed, C8 Corvette Stingray owners should observe an increase of 17 horsepower and 25 pound-feet of torque on a dyno, Halltech says. That means a C8 Corvette Stingray equipped with the optional factory Performance Exhaust and the Halltech Hornet 518 intake would produce roughly 512 horsepower and 495 pound-feet of torque from its naturally aspirated 6.2L LT2 V8 engine.
This intake was designed and engineered for the C8 Corvette Coupe only and will not fit on Convertible models without slight modifications to the access panel under the trunk carpet. The unit is priced from $795 USD and is available to order from Halltech’s web shop now.
aFe Power intake for C8 Corvette Stingray
This intake is similar, though still quite different, than the carbon fiber cold air intake offered by aFe Power. The aFe intake (pictured above), which was released in 2020, features a lightweight carbon fiber construction that improves the look of the vehicle’s engine bay with the engine cover lifted. While the carbon look is certainly appealing, this intake is quite a bit more expensive than Halltech’s at $1,336.65 USD. The aFe intake also does not result in a claimed horsepower increase.

$800 is better than $1300. But I opted for an Attack Blue filter element at $130 for a modest 5hp increase or so.
I wanted to be able to say , yeah it has 500hp.
I’ve been considering the attack blue for my 2021 Z51. Are you happy with the product – and – did you notice any real power increase or are the specs just a number and bragging rights. Thanks !!
The graph does not top 500hp at all for the halltech product being advertised….. please explain.
It’s rear wheel HP, therefore you wouldn’t expect it to top 500
Bogus dyno report! Put a load on the dyno and see the results. I’d say more around 400 hp with that airbox to the wheel.
It is a load dyno. Done by an independent shop on a customers car.
The dyno records the “Rear Wheel Horsepower” The conversion from Rear Wheel to crankshaft power is around 12% on this Corvette. In the past, with the drivetrain eating up horsepower, the loss from the crankshaft to the rear wheels was around 15%.

That hp figure is at the wheels not the crank, which is where the 495 figure from Chevy comes from
Are you sure ? Everything I’ve ever read says that manufacturers always quote crankshaft hp. Car and Driver dyno’d a stock C8 and reported 440 wheel hp. Hennessey got 466.
Manufaturers actually have SAE dyno their new engine platforms. Done with the engine on an engine dyno that records crankshaft (or flywheel) FHP.
Since no one in in their right mind would allow their car to have the engine extracted, just to record the HP at the flywheel, the chassis dynos, Like Superflow, DynoJet, and Mustang dynos used varied methods of recording the horsepower at the rear wheels, which is attenuated by frictional, and inertia losses. In the case of the C8, it appears that there is a loss of approximately 12% when comparing engine flywheel to rear wheel hp.
We own 2 C8s; the one that had the very first beta version of our intake, was the dyno comparison we posted above. My C8 will make its way to LPE for before and after, but we are also installing the pRT Carbon intake manifold, and LPE throttle body. Just waiting for them to arrange the appointment.
Hope this helps.

You are correct. Actually done at the SAE dyno. Engine out of the car, and recorded at the flywheel (crank)
The afe intake comments do not appear to be accurate…the only reason I actually looked is because I was shocked that there would be no claimed increases from afe. Upon my quick look, I see they have a $770 intake that claims 12/10 increases (c8 ‘track series” intake, in addition to the “black series” intake for $1,250…which also claims 12/10 increases). They also have dry filter options at the same prices with lesser increases.
Regardless, it’s good to hear about the new Halltech, but this article is otherwise misleading…if you’re going to mention any other intakes here, why not just list the other current-market options (afe, corsa, k&n, etc.) so ppl can look them up and do their own research?
Up to 17 hp increase which actually means 0-17
I’ve done every mod possible (like a fool) to every vehicle I’ve owned since 1969, including diesels.
Maybe a little more intake noise but the HP and torque increase numbers are bogus.
A aftermarket airfilter might help a little but a aftermarket intake is a total waist of money.
BUT some will believe blow the money the only real gains are a lighter wallet.
After years of disappointment blowing hard earned $$$ on mods, my C8 is staying factory except maybe the BLUE airfilter when it’s time to change it, maybe.
Some people just don’t understand the principles of fluid dynamics and filtration efficacy.
OK. Please elaborate. Help the rest of us understand.
Dru is at the Ron Fellows driving school this weekend. He will reply Monday.
Thanks,
Jim
Paragon Performance just posted this install video.
https://youtu.be/LZQ5rEzimzU
PARAGON PERFORMANCE has confirmed the Halltech Hornet fits the HTC beautifully!!! The only modification is to simply remove a single rivnut. The access panel then goes back in place, as does the carpet kit. They will be doing another amazing install video shortly. Check out their website to purchase the product and watch for an install video shortly.
As Dru indicated, a new video will be released shortly. Such an easy fix, and thanks to Paragon for their easy solution. Their customer has just increased his HP by 17.1 RWHP and 25 lb-ft. torque.
