JLT Intake system highlights, video results.

Hey everyone.

It's been quite sometime since we released our system and there's been many results posted by shops/customers and such on the net.

I wanted to make this post to highlight them and put them in one post.

Our kit is a complete replacement kit, heat shield with grill duct, tube, filter etc.

Utilizes a 120mm MAF housing, it's a huge 5" opening at the filter side and necks down to 4.5" at the throttle body.

I like results, I like videos so here are quite a few we've gathered from the net.

Here's our own personal testing videos (3 total) These were done with our own tuner package (SCT X4), tuning is done by a local tuner we've used for years. Brent Hughes from DTP Racing here in Chesapeake, VA. Brent has been in the business for over 20 years and tunes nearly all makes.

These next post are all from Facebook where I can't hotlink the videos.

I would like to point out Johnson Tuning and True Street have no affiliation with JLT. They are not even dealers of our line. These were post they tagged us in on Facebook.

We strive for 3rd party results with every product we offer, we believe they mean a lot more than any single manufacture claim. I will continue to update this thread with more results as we stumble over them. Feel free to ask any questions you may have, enjoy the noise

I don't get why these intakes don't make a difference when paired with headers. Puts out the same numbers as stock intake with headers. Both tuned of course.

Not according to the post directly above yours.

Read the post again. JLT added before headers. Stock intake with headers and JLT with headers put out the same numbers.

I read 467>477>488>506/stock>tuned>JLT>headers.There is no stock intake with headers number.

Exactly.. it's not posted in this thread.

Where? Are you comparing this to another car?

Interesting. I tried finding that True Street Motorsports video on Youtube but couldn't.

It's on Facebook

Ps. You can't compare one cars dyno to another cars dyno on a completely different dyno. Look at the gains, the differences.

Let's see the link.

All testing and comparing must be done on the same car, but if
$349+ tune = 485RWHP OR $2000 + install + tune = 485 RWHP
what's the better deal?

Anyway, I found more results on the same car and the headers made a pretty good gain. Cooler air and this is a 500 NA car

And another

I cant tell from the above what the gains are from the intake. It looks like 12 WHP but you have to get a tune to adjust for the large piping?

But it looks like a tune alone can get 15 to 20 whp(from other threads)?

I cant tell what gains the intake actually makes.

Sorry if in being dense.

It also seems like the dynos posted all have oddly low baseline power.

In most of the test we've seen the intake is worth 8-12whp over the stock setup. We're pretty happy with that when you consider the stock setup is already an open element.

I've seen these cars dyno stock 440-480 depending on the dyno and car.

Thanks for sharing the results. Dyno to Dyno can be apples to oranges. Due to calibrations, temperatures, altitude, fuel, etc the numbers will vary. The best way to view the intakes effectiveness is what it did on one specific car on the same Dyno. Then take an average of all those cars to see an approximate gain that you might see on yours.
