Now you need to make it a true CAI by blocking off the "leaks" that let hot engine compartment air be ingested. I got the K&N CAI because it had a heat shield. However, it has several open areas for engine bay air to get past. So I purchased some ThermoKing insulation at Lowe's and opened up a larger air passages. I've been doing great during the hot Texas Summer!!
Here is where I made a larger opening in the fender so the engine would draw air in from behind the fog lamp.
Also, modified the K&N bracket to prevent chaffing the power steering hose.
Here is the "air box" area before the filter and induction tube goes back in. I used GM touch-up paint I had to make sure there was no bare metal.
Also blocked the rest of the openings to make it almost air tight with the hood down. I had to use a plastic tie wrap to keep the foam to stay put around between the shield and the filter.
I worked the adhesive-backed insulation blanket around the induction tube and made sure it was secure with some 18-inch tie wrapes. Total cost was $16. I don't have a thermo couple to take measurements but I know this has got to provide a significant benefit. I've been configured for several months like this and the commercial foam products have showed no sign of not being up for the job - including some track time. I've also added some more insulation around the IAT sensor to make sure flow off the radiator is not affecting it.
