        Hey everyone, Justin with AmericanMuscle.com and this is my quick look into the C&L upper intake plenum fitting the two valve, 4.6 liter motor found in all '96 to '04 Mustang GTs. C&L devotes a majority of their time and efforts into designing and developing Mustang specific intakes using flow bench engineering and have been doing so for over 20 years now. Whether it's a cold air intake for your Coyote Mustang, a matte housing for your Foxbody or Cobra, or an upper intake plenum here for your SN95, chances are C&L has you covered. Now if you guys do want to see more from C&L, including other project car builds and other great Mustang content, you should definitely check out our YouTube channel sometime, click the link below to subscribe if you haven't done so already, and while you're there, take a look around and drop us some feedback. So the goal of the C&L upper intake plenum here is to maximize the airflow into your two valve motor, increasing not only your horsepower and torque, but also your throttle response. Now in fact, don't take my word for it, we have a ton of customer reviews on this product in particular, and I definitely encourage you to click the link below to head back to the product page, if you're not there already, to read up on some of these reviews. The plenum is made right here in the USA using high quality aluminum for the construction. Now, it is a carb certified 50 state legal part, so my SN95's in California can take advantage of this part. Now, if you guys do read those customer reviews like I just told you to, you will notice a majority of our customers actually pair this plenum up with a 70 or 75 millimeter after market throttle body. Now granted, you guys can take advantage of this part using your factory throttle body. But if you do want to maximize your gains with the larger volume and larger diameter, I highly recommend you go with an after market throttle body of your choice, especially on heavily modded two valves, which you'll really see some solid benefits thanks to the C&L. Getting the new C&L plenum installed isn't necessarily the hardest install in the world, but you will need to take care of a few different steps, including transferring over your EGR and intake air control valves over to the new unit. Because of this, we are going to call this install roughly two hours from start to finish using basic hand tools, but if it takes you guys a little longer, don't get discouraged. Keep in mind, we always have very detailed product breakdowns and installation breakdowns and installation breakdowns available on the product page. So if you do get a little jammed up, you can always reference those, or you can always reach out to one of our Mustang experts by phone or by email. So if you're looking to further open up the intake on your modified or stocked two valve SN95, then be sure to check out the C&L upper intake plenum, available here at AmericanMuscle.com.

        Maximum Airflow. The C&L Upper Intake Plenum is specifically designed to improve the airflow into your 2002-2004 GT's 4.6L two valve V8 engine to maximize airflow for a noticeable increase in horsepower, torque and performance.

        Perfect For Larger Throttle Bodies. To really take advantage of a larger than stock throttle body you need a larger than stock intake plenum. Just by installing a C&L intake plenum in combination with a 75mm throttle body on a mildly modified Mustang you can see at least 8 more rear wheel horsepower, and as much as 15 more horsepower on a more heavily modified Pony.

        Made in the USA. Proudly made in the USA from the highest quality materials available, this C&L Performance Intake Plenum has been extensively flow bench tested and engineered to out perform the competition.

        CARB Certified. Best of all this C&L Upper Intake Plenum is 50-state smog legal under Carb EO# D-640-1 for 2002 through 2004 GT models.

        Application. This C&L Upper Intake Plenum is a direct bolt-in replacement for all 2002 to 2004 4.6L 2V Mustangs using a Stock, 70mm, or 75mm Throttle Body and will clear stock hoods with only a 1/2" height difference compared to stock.

        What's the difference between the 02-04 to the 96-01?

        • Between 2001 and 2002, the vacuum lines that went to the plenum changed. The two different C&L Upper Intake Plenums are essentially the same item, they just have different vacuum configurations for the two different years.

        Hi I currently have an 03 GT and I was wondering how I can get the 96 to 01 plenum to work on my 03? I had it on my 00 GT till someone totaled it.

        • The C&L Upper Intake Plenum will work on your 2003 GT. As far as swapping plenums, we suggest doing some further research online.

        i was reading on the american muscle "when should you upgrade your throttle body" that with mild bolt ons like a CAI and exhaust its not good to exceed a 70mm throttle body size but i hear a lot of people saying in the comments that they paired this upper plenum with a 75mm throttle body, i bought a 70mm, is a 70mm good with this plenum with mild bolt ons or could it have handled a 75mm throttle body with mild bolt ons (CAI and exhaust) with no issues? did i make the right decision using a 70mm throttle body? will it create back pressure at the interface and if it does is that back pressure a good thing if eddy swirls and turbulence are created?

        • The C&L Upper Intake Plenum can work well with a 70mm or 75mm throttle body without issue. The issue that decides what size throttle body to utilize comes down to the work done to your vehicle, as a more heavily modified vehicle will draw enough air to utilize a 75mm, however a lightly modified vehicle may see some benefit at higher RPM, it will loose some low end power, and throttle response if paired with a 70mm Throttle body. We typically do not recommend the 75mm for cars with anything less than CAI, headers, and cams, as performance gains tend to be negligible going from a 70mm to a 75mm on these setups, and throttle response will tend to suffer. On cars with mods as described, airflow is significant enough that we see good gains going with the larger throttle body.

        Work with Vic Jr? Would the C&L plenum work with the Victor Jr intake and if so, would it be better than the Edlebrock plenum that is suggested with the intake? By sight alone , I see it doesn't match, so is there an adapter to make it work or is it just not possible?

        • It will work with victor Jr intake,, you just have to get the adapter plate for the plenum to bolt onto the intake. I have a 02 4.6 that I'm doing the victor Jr intake on. MMR is the only place I've found that offers the adapter plate

          Completely worth it

          Amazing product and I'm glad I went with it. Woke up my 04 GT for sure. Low end torque isn't what it was, but it's hardly noticeable, but the top end.. that's where this shines. Feels like you're hitting boost at 4Krpm and she keeps on pulling to redline

          More Responsive and More Feel

          One of my favorite purchases I have made from American muscle! The sluggish feel is no more when you invest in the CandL Plenum, you can really feel the car move in the high ranges of the rpm. also bought it because I live CA and not to many companies make CARB certified plenums that are legal in CA.

          More air

          The plenum along with a 75 mm. throttle body gave the car better throttle response. I was pleasantly suprised the car idles better than stock.

          Catching on the butterfly valve

          Overall I LOVE this plenum. Great gains and so much better response. One glitch was I had to dremel it out a little as my 75mm TB butterfly valve was catching on it a little, not so bad that it would get stuck but rather "sticky". You could feel it in the pedal basically. But a few minutes of refinement and all became well. Excellent performance modification!

          I should have bought this sooner, really wakes up the car in the higher rpms, especially when paired up with a 75mm accufab throttle body. I highly recommend.

          Recommended purchase

          I don't know if it was the combination of the plenum and the SR performance 75mm TB that I installed but the throttle response and low end torque woke right up! Definitely recommend this product without any reservations. Was super easy to install and took around an hour because I let my 7 year old son install it (with my help and supervision.)

          Excellent performance increase. I got the wrong one. I was sent the one with the 5/8" pcv intake and I needed the 3/8" one. A trip to Home Depot and a 2' piece of 5/8" hose and the problem was solved. Highly recommend.

          C&L Upper Intake Plenum (96-04 GT)

          02 Mustangs with a solid EGR line might find it difficult if not impossible to add a the recommended spacer plate between the plenum and the intake manifold unless you decide to cap off the EGR. As an alternative you can add a 1" spacer between the throttle body and the plenum. If you are going to replace your throttle body with something larger, it is the perfect time to do so. After installation I was very pleased to hear the hiss that was coming the performance air intake and impressed with the increase in power. I recommend a PCM Programmer or Performance Tuner to really take advantage of the increased air flow. Thank you American Muscle

          A little better than stock

          It took about an hour for the install... Installed Professional products 70mm TB with it... Already have Bama tune.. Small HP gain hardly noticeable.. The only thing i was impressed with was the throttle response from the New throttle body because my stock one was sticking... If you got some extra money and just love tinkering with your Mustang than this is pretty cool to just add to a list of mods. I guess a few extra horses can't hurt...
