I know the purpose of heat shield. My question is I see the k_n system has a full fit heat shield, the other intake systems kinda do. Some don't at all. How much does the heat shield really do?

As far as performance? If anyone has actual results. Besides those cheapy ones on eBay. You pay for name brand for a reason

Honestly, it's hands down the biggest gimmicks in the aftermarket automotive industry.

The little half piece of aluminium covering the filter makes no difference in ambient air temps in the hot engine bay.

However, the manufacturers realize that some people will buy into it, so they do it anyway.

Go with an Injen Intake, it will make the same power as K&N for about $40 less.
