Upper Plastic Intake Manifold (99-06 4.3L Sierra 1500)Find parts that fit my vehicle

Best plug and play intake I've had

Doesn't take long to install and you notice improvements almost immediately after. Throttle is more responsive, more power out of the gate and way more power in the long run too

Great Fit.

The part was delivered in a timely manner and is an exact fit.

Truck runnin strong

I really appreciate the help from the man who help ed me get the 10 off. I could never figure out how to use this. Truck seems to run like a top now. Only took like 30 to 45 minutes. Shipping lightning fast its american trucks. Always satisfied everytime!

It fits perfectly

My line was leaking and it digs it perfectly. After some tutorials on YouTube, I was able to fix it.

Great quality

The only thing I didn't like about this process was that GM puts a solid plastic cover in place that needs cut out. Once I awkwardly positioned myself to cut out this plastic, the filter slipped right in and the cover popped right into place. Being able to clean the permanent filter in place and then adding the pre filter showed immediate results in air quality in the cabin. The next filter that needs to go into place should take less than 5 minutes to swap out now that the retrofit kit is in place.

Great quality

I could tell a difference almost immediately after I cleaned out the permanent filter and put this pre filter in place. This cover popped right into place and the filter slid right in. The only difficulty I had was cutting out the solid plastics in place from the factory. It is in an awkward spot, that was the only difficult part. Now that I have the retrofit in place, it should be a breeze to regularly replace the cabin filter.

Throttle body

Seems to be working good good throttle response quick and fast frlivary

Resolved my throttle body issues

I was having a difficult time with a sticky throttle body that is apparently a common issue. The dealership was trying to charge a significant amount of money ‘fixing’ this by replacing with the original part. I instead bought and installed this and it’s worked flawlessly!

Smart choice and easy install

I made the right choice with purchasing this one. It was easy to install and I didn’t need to do anything with the programming. Just reattached the battery after I was done with the install and turned on the truck and off I went! I was having issues with my 2015 going into limp mode and after researching they said it was the throttle body. They must have been right no issues since I installed this new one. I only gave it 4 stars because it doesn’t come with a new gasket. I didn’t realize it and had to go to 3 stores to find one. I would have paid a little more for this product to include the gasket and it is would have saved me the time and frustration of having to go pick one up.

Insane audio plug and play

I would not purchase this unit . I ordered it on Feb and had to cancel it because it was taking so long to get.I understand the carona virus. But a few weeks ago I received an email from AT that shipment wouldn't be until August! Very unacceptable. While on there web saw in stock. So I re ordered. When installing it I went to install the mike well low and behold no place to put it. Enough said I'm returning it. Pretty bad quality control.
