What's up with these 20+ HP performance mods I am seeing on eBay. Seems to be offered for many vehicles. I've read through most of the posts on this forum for the last 12 months but I see no mention of this so called mod.

I surmize their $3-$8 mod and some as high as $35, are the 4700 ohm resistor inserted in the cold air intake sensor circuit to trick the engine controls into thinking the mixture should be enriched.

What's the reviews/thoughts on this?

Edit: Sorry, no ebay links. Rule 5 of Forum Rules.

Here is an email I sent to the seller. I hope this helps.

Q. Is this product made specfically for the RX300 or the 1MZFE engine? Do you have a dyno test on a RX300 AWD or a 2WD?

A. This is not a product that specific made for the RX300. The module applies to all car that generally have the IAT sensor, and that is MAP based car. Take a search of the Apexi S-AFC controller/JET chip and you will see that we sell a product that is basically provide the same function with much lower price.
Email me if you have more questions. Thank you!

Sort of what I suspected - sounds like the 4700-ohm resistor mod. Wonder what the down side is on engine longevity.

Decrease your gas mileage, and get marginally better performance... plus the added wear on your engine.

If you want to increase your horsepower, get the Weapon R intake combined with RMM Exhaust. Your RX will thank you
