So the fuel rail didnt fit exactly correctly on my 2002 Silverado 2500 hd 6.0. However I was able to make it work and let me tell you. She drives and idles so much better!!
Absolutely amazing product and an even better customer service!

This was my first purchase ever from 1A and they have won my business for ever. The quality of the products and the shipping speed was amazing. One of the bolts of the intake manifold broke before reaching the recommended torque. When I called, it was expeditiously resolved by Anthony from the quality team and a new part was sent overnight! Based on how a company responds when there are issues, you get the philosophy behind the business! Great job 1A! I look forward to more business and using your helpful videos!!
Good intake manifold poor fasteners
Alan
October 22, 2020
Intake seems to be of good quality. Had to take a razor blade and clean off excess flashing from around intake ports. After torquing bolts down on the first pass I then increased torque to 89 in lbs. on the third to last bolt the bolt snapped off at the shank of the bolt where the threads start. Luckily the bolt was sticking up enough to get locking needle nose on and extract. Also wondering what the difference is between this intake and the one listed for 500 some dollars.

Worked just like the OEM. Much easier to replace the old one then try to clean it up for my new engine.
Great price. Must be why

1999 GMC Sierra 1500 Everything pretty much fit up perfect. The 1aauto YouTube video explained to tighten to 44 in/lb on first go around and 89 in/lb on second. First time trying to install I broke bolt #2 on tightening diagram. Luckily was able to remove broken end in engine block. Second attempt I UNDERTORQUED and this time bolt #5 broke at 75 Inch Pounds. Very disappointed. Im assuming the $500 Dorman version they offer has decent bolts. Merry Christmas
So far so good!

Seems to be good quality, install went easy. I did break a bolt but they were quick to send me a new one. Thanks!
Decent manifold Ikea furniture bolts
Phillip
May 24, 2021
The manifold was easy to install and all the parts transferred over nicely. However the bolts look like they are out of some Ikea furniture. I read a review that said the bolts are garbage and they had one break on them. And sure enough, I didn't even get through the first torque sequence (44 inlb) and one of the bolts broke. Luckily it came right out after removing the manifold again. But I had to rig it in a pinch because it's my only vehicle. Would highly recommend getting different bolts if you order this manifold. Not sure why they couldn't have used better bolts even if they did have to charge a bit more... What a headache.
As of right now! Will update later

After reading reviews about the bolts snapping. I took extra precautions and went to 36 inch pounds on the first pass. After finger tightening all the bolts in order per video. Was on #3 when bolt #1 shot out. Lucky it snapped high enough that I was able to extract it. Poor quality bolts.
Bolts break. good manifold though

manifold itself fits perfectly but the bolts suck ass. One of them broke at 44 inch pounds inside on my cylinder head. (see picture) and after I took another bolt and put it into a vice and was able to twist it in half with one finger using a 1/4 inch ratchet. Also I do not think the diameter of the bolts are correct because when I went to extract the broken bolt out of my head. there was a lot of wiggle room. Please upgrade the quality of these bolts and stop giving out cheap Chinese manufacturer quality bolts. If you do buy this intake please do yourself a favor and upgrade the hardware, It will save you a lot of time.

Manifold seems pretty solid just these cheap bolts it comes with makes the experience terrible. Broke on on less than 40lb/ft
Do not use these bolts!!!
Brian
April 26, 2022
Intake manifold itself is okay; all in all fairly solid, but my fuel injectors didn't go in as snug as they did in my stock manifold (even after replacing o-rings) and I had to troubleshoot several vacuum leaks from gaskets that didn't sit right at first. Bigger problem: as mentioned in several other reviews, the bolts that come with this manifold are not strong enough for the torque required. I had a bolt break before getting to the second round of torqueing, and because it broke below the surface of my engine block, I'll have to spend another $100+ on tools just to remove it before I can reinstall the part with better quality bolts (which I'll also have to buy separately). I would only recommend buying this manifold if you are on a tight budget and are confident you can find the right-fitting, better quality bolts elsewhere. Otherwise, it just isn't worth the frustration.
Seems okay

Seems alright, very tall though. And the gasket design worries me a little bit but all in all it seems like it's gonna he decent for the price.

Actually really happy with this intake and hardware. Honestly the reviews about bolts snapping freaked me out to the point that I almost didn't purchase but I did. Quickly found out that spec of 44 inch lbs is very light and I'm pretty sure all of these people that are breaking bolts are just over torqued which is obviously bad for plastic intake manifold anyway so it's probably a good failsafe. Bolt is cheaper than a whole manifold. This intake definitely deserves a better rating then it has! Buy it and torque it right, you'll be happy!
Improved and smoother acceleration with more power

I broke the retainer tabs for my MAP sensor on my old intake manifold and the original style manifold is no longer available for replacement. I was hesitant at first about this updated design intake manifold, but now I am very impressed by this new design. I definitely feel improved and smoother acceleration with more power. I'm very happy with this updated intake manifold.

March 25, 2024
Great product. Once we found the video that explained the location of the sensors (the original has different sensor positions) everything went together just great. Already noticed an increase in acceleration, doing a fuel MPG test to see if anything changes there. I would always include a link to the video, it is well done and explains things even for the non-professional mechanic. I hope i never need another one, but if I do, i would buy it in a heartbeat. Keep up the great work.
Good replacement at a great price

When I ordered the product I did not realize it had been redesigned and not a duplicate of the original. I did not read enough into the product description. I am OK with the redesign but, would have been nice to understand the differences up front. I understand the moving the hose that comes from the valve cover from the center of the intake manifold and putting it at the front. Makes having to move around some hoses and stuff but, makes sense. Then comes moving the MAP sensor. Maybe moving it helps? But, when you have to locked it down with a screw, changing out the part will not be fun. Seems like we will have to loosen the intake manifold. Which means we will possibly need to replace the gaskets that are not standard. If I took the car to a shop they would not know what to do. Thankfully, I replaced the knock sensors while I had it broken down. (should make a strong recommendation about replacing knock sensors, cable harness and gasket). did not know where to use the black cord

I am writing this review after one month and roughly 2000+ miles since installing the TRQ manifold in our 2003 Chevy Suburban LT. Generally, it would be nice to wait a year... Seems to be working exactly as described. I was concerned about the overall performance and quality since the TRQ manifold is about 1/3rd of a Doorman and/or other retail brands are as much as 3x to 4x higher than the price of the TRQ. So far no issues. I watched both 1A Auto's and TRQ's Videos (highly recommend that since there are always minor particular differences among these engines) and the process went very smoothly. Please note - do not torque down the manifold prior to attaching your throttle body as one video demonstrates - there is not enough clearance on some Chevy models to "clear" the water pump as you reinstall the throttle body after the manifold in bolted down. If you attempt this step after bolting and torquing the manifold down you will not be happy. We also replaced the knock sensors (highl
