props to the maturity of this forum when nobody makes a crack at the name "bong" try postin that anywhere else on the web... sry to get off topic

There are a host of problems with their lead-proof (really only mildly lead-resistant for an undetermined amount of time) O2'*. If you do a search, you'll find them easily. I found several yesterday alone after this topic started.

Your Denso may look different from a Bosch, because SOME Bosch'* are Denso'*. Not all. That was put out as a general warning to people that you sometimes don't get what you expect.

There aren't many cars on this Forum that would benefit from the specs and reasons you posted on the Denso'* behalf.

Blazin.. I see you mention a couple of the benefits of a denso and they are the "best you can buy". I also see others mentioning denso failures. Have you seen any failures in the Denso'* like the others. It seems you are the only one giving them kudos.

I'm not looking for a debate, merely gathering more information.

What car isn't going to benifit from a 'faster' sensor? Also our cars are supercharged... It is quite easy to up the boost with a simple pulley, so why wouldn't 110 or even 116 octane benifit someone that wants to run more boost at the track?

The only 'Denso' failures you are talking about are a sensor that costs $20 and comes in a Bosch box. So don't buy a Bosch and you won't get a shitty O2! Buy a box that is more money and says Denso on it. (to answer your ? BillBoost37)

Yes that is somewhat true - they are not fully lead-resistant. Running lead gas will cause its lifespan to be shorter but even with seeing lead gas they will last just as long as an AC Denco not seeing leaded gas. Try running leaded gas on a AC Delco or even better yet a Bosch and see how long they last.

My car has seen 2 full tanks of 110 - no problems so far. Ask the W-Body crew and see how many are running leaded gas with these with no problem. I even know of one Intense member that has over 1000 gals. through his car and is still on the same sensor. Doesn't sound like much of a problem to me. But what do I know?

Blazin, 99% of the cars here don't use leaded gas. But what do I know?

Again, what are the performance benefits of the Denso? A millisecond better response time? What'* that equate to in terms of performance?

How is that 'better' than the OEM? Sure, there'* more counts per second, but WHAT does that do for hp/tq, and performance?

<------- rollin' back at ya!

<----- Me too

And 99% of you are losing out not running leaded gas at the track. Their is a reason I can run a 2" pulley with 0 KR one of them being leaded gas. More boost less knock - sound good to me! But what do I know?

The performance benefit with a Denso is being able to run LEADED GAS!!!!!! Yet again... "More boost less knock - sound good to me!" Isn't that everyones goal to run a smaller pulley with no KR helping them get the quickest E.T.? And on top of that for normal operating conditions it is more accurate and faster. So I think that is now +2 on a normal sensor.

I see your and raise you ! haha j/k

Ok..it'* time to put our maturity hats back on and stop our kidding around.

Wren'* meaning was most don't go to the track or run leaded gas.

Thanks for the laughs and good info everyone.

Blazin, let me get it a little clearer:

You run your car illegally. 99% of the cars here run LEGALLY. Your preference.

I know I don't run a cat (Shhh... don't tell anyone ). But it is quite simple to have a setup that you can change between a 'race pipe' and a cat. Then you can be legal on the street and have the added benifit of running higher octane at the track with a smaller pulley.
