Its not even a seal issue at this point because frankly, they don't line up enough to even begin to be what I consider a seal.

With the bottom not bolted down, I am assuming you have enough play be be able to pull it up nicely into the top lip?
I have been running this for about 2 months.. It's been fine.. and you hit the nail on the head..

Chuckster, it just occured to me, what about the fog lights? Did they still line up okay?

Funny thing here...My fogs did not line up well with the STOCK Inserts in there.. It got better After I installed the Vararam with the Inserts attached..

I recently received their "grey" filter and the gasket kit to install it. I'd say that was the best filter fit (good seal) I've seen on my Vararam to date. It also was fairly painless. I did not like the foam filter and K&N with gasket kit setups.

IMHO slip fitting just adds another point of error in the process, but being that tolerances in the Vararam/Vette mating aren't good... Either way, sealing the plenum isn't a concern. I wanted the little gap there to give water splashes somewhere to go other than my engine.

I took his advice, and have been running them this way for about a month. I have no problem w/ fog light adjustment, as they're solid when connected to the upper section. They will never become dislodged from the fascia because I left on the outer bolt attached(only removed the inner bolts).

Slip fit is not a point of error.. it an additional area of margin.
Having the unit fixed with no play end to end actually is a crap shoot to a proper seal. Leaving the bottom open allows the Rubber Straps or bolts to do their job.. which is pull the unit together for a tight seal.. If you are trying to yank it away from the facia because it's bolted you are going to tear something.. or get a crappy seal..

It wasn't hard, but it did take some careful attention to detail to make sure the air filter was properly sealed. Vararam recently redesigned the whole affair and it is some better, but it might come up a little short when you try to mate the filter/airbridge part to the front scoops (maybe-depending on each car's particular dimensions). If you use Chuckster's mod or just add the insulation to take up the gap it will work fine and yes, you'll really notice a definite improvement.

I think Chuckster's explanation says it all. There are variances between the different C5's dimensions that cause some of them to wind up with their front facias a little further out front than others. This causes the scoops to come up a little short when you try to mate the scoop assembly to the filter/airbridge assembly. However, in Vararam's defense, they did provide some spacers which approximate the distance which I see in Chuckster's pictures, which if used would allow you to bolt the scoops to the front facia, thereby making it stand off about 1/2 inch from the fog light opening and allowing a closer fit to the filter/airbridge assembly. This would place the scoops closer to the filter assembly so no further gasket would be necessary. However, I'm not really sure that it's even necessary to bolt them in the first place, because once you reinstall the front radiator shroud, the scoops are pretty well pinned in there and aren't likely to move much, if at all. It still gets plenty of ram air force from forward motion and would still provide an increase in air pressure to the intake manifold with the result in increased performance.

By the way, I was changing from a very low restriction K&N zip tie mod (which itself made a huge difference from the stock air box-see picture below) but the vararam clearly improved the performance, especially as the rpms go up....Definitely worth the investment imho.

I'm on holidays this week so I am going to try to install it Good news on the performance gains

Default Foglight lineup

I just installed the Vararam B2 and had issues with the foglight fitting into the holes. I ended up pulling the fog light housings out and drilling another hole in the mounting bracket to drop the down about 1/2". The are perfect now after the minor adjustment. I screwed the housings to the bumper and had no issue sealing her up tight. I do have a small issue at low speeds where the car seems to be jerking a bit. Anyone have any ideas? I rechecked all the clamps to make sure there wasn't an air leak somewhere..

I also did the PCM reset so it would re-learn the air / fuel mixtures.

Default Vararam update

I called Vararam Tech Support with my issues. They are sending me a new upper air box with a diverter valve in it at no charge. He said that since I had removed my screen on the MAF this would compensate for that. GREAT CUSTOMER SERVICE!
