Just as the title reads ... will this hinder/decrese performance a significant amount?

How about the post-cat sensors?

Thanks for any input.

I got my pre-cat sensors from AutoZone. Can't remember how much I paid, but it was reasonable. I was able to notice better idle and throttle response after replacing them. Haven't done the post-cat sensors as they are just for monitoring. I can guarrantee MAF cleaning in conjunction will yield favorable results. Let us know how it turns out for you.:)

Thank you!

Part number is Bosch #13477.
This the number from the box. Don't know if AutoZone has it's own number for them. I also found them at Advance auto parts.
