    I appreciate you trusting us to be one of the first to get my front inlet covers. Wire ties definitely make it easy if you have the need to remove & clean or if you track your car. They look AWESOME, can I say factory.

    Thanks again!

    Welcome. I would suggest to anyone installing inlet covers to find a buddy with a lift if you don’t have one. It will make the install much easier and less painful. lol. I did it the hard way and will pay for it tomorrow. Thanks for a great product Rich. It was worth the wait !

    • know everyone already is thinking about this or they should be. Lot of testing was done to determine the volume of airflow needed in all operating conditions. You restrict flow over a heat exchanger in marginal conditions bad things will happen. The other part is the damage that could be made by impacts of everything from rocks, big nasty bugs at high speed etc to the fins. This is going to be a tough one for me to address on mine as it will have more of a heat load and I hope this issue is vetted out completely.

      On my C7 Z06 took the seal out along the back side of the engine bay to let air exit between the back of the hood and the engine. Made a difference in summer stop and go here and highway is awesome. Bad part is after a car wash the steam comes in big time so air is on recirculate.

      My car is not driven in the rain either since the new paint and engine modifications.

      • It was a little pain for a lot of pleasure! I hear ya. Lol

        We are getting older and sitting on the ground isn't really fun anymore. Thats why I made the parts fit perfect, it makes the install go faster.

        Cheers!

          Hi Busa Dave,

          Not sure who this is directed at but my front inlet covers have the most open area of ANY perforated metal or plastic @79%. Also several MECF testers verified no raise in normal operating temps.

          See Jags post: https://www.midenginecorvetteforum.c...sters-feedback

          He verifies his normal temp stayed the same, also Tbob noted this: I did a road test and found no discernible temperature issues both in town and on the highway



          Thanks, this is a very important issue for every C8 owner.

            I don't know about earlier generations, but the radiator on the C7 is a couple of feet behind the grill in the front fascia. Not only does that make it less likely to get struck by debris, it means if any of the fins are bent you won't notice them. The C8 radiators (A/C condensers, actuall) are right smack at the front of the car, and brightly metal, so any bent fins are quite noticeable.

              No it was not directed at you at all. After reading most of the posts the concern seemed to be skewed to aesthetics rather than performance. Performance can only be verified in controlled conditions with testing to validate. I am sure the modeling of the surface area was done and the flow verified in a wind tunnel by GM then field testing in a wide variation of ambient temperatures--who knows how many changes were made as a result.

                I ordered the Grill Mesh Kits from custom car grills and installed them in about an hour. Pretty easy. The website has video instructions and the only thing I had to do different was take off the front splitter since I have a Z51.

                I got this set because the powder-coated aluminum is honeycomb shaped and matches the grill mesh along the back window and the rear mesh below the back bumper. They install to the inside of the grill covers so I can still clean those parts.
                Does the set from Custom Car Grills have rubber trim all the way around it? If not, does it need it?

                  No they don’t and they don’t need it since it’s installed behind the grill

                    It does not. I will be picking up my car on Friday and most likely laying underneath the front of it on Saturday doing the install. I believe they have a YouTube video on their website of the install.

                    • I noticed that Custom Car Grills now has the inner grill mesh set available. Just ordered. They have videos for installation of both the outer set and inner set. Removal of panels under the grill is the same, but if you have a Z51, you also have to take off the front splitter (not shown in the installation video).

                      The inner set does have a rubber edge on the bottom to keep from rubbing the panel below it. It is a little different configuration than the outer set that does not have any edges around it that it would rub against.

                      • I went ahead and ordered the full set from Custom Car Grills this morning. It's already on the way.

                              Here are some pics of the install of the inner screen covers. I have already installed the outer ones.

                              First: remove the splitter (Z51) and the cover in the center

                              Second: pull down but do not remove the covers on the side.

                              This the the part. The protected edge goes on the bottom.

                              Third: pull down on the side covers (they will not break) and slide the screen cover behing the grill cover.

                              Fourth: Set it in place and then use the ties to attach to the grill cover. (You need to have some manual dexterity in order to get one hand behind the screen and one in front to insert the ties and tighten them. I left them all loose and then tightened them one everything was looking like it should

                              Put the center cover and splitter back on.

                              • ELB2020VETTE: Nice job. I bought the exact same ones. Waiting to install once my car is delivered in 2 weeks. Thanks for the instructions. About how long did the whole project take??? Great photos too.
