Mass airflow sensor

[Odub87]

i also found a mass airflow sensor for 3.1's on the summit site, but it says its for cutlass supremes and achievas. will it work on a ciera, or not?

here's the site: http://store.summitracing.com/egnsea...115+4294924755

that really expensive.. what mods do you have done to the car???

[Odub87]

k&n oem replacement air filter
bosch plantinum +2 plugs
lol

i know it's expensive, but will it work?

[bszopi]

What are you hoping it will do? If you aren't bringing in any more air, then there is no reason to upgrade the MAF. There are a ton of decently modded cars still running stock MAFs. And I could be wrong, but I'm pretty sure on the Ciera, the MAF is integral to the TB, so that wouldn't work anyway.

Since it was just brought up in the last week... http://60degreev6.com/showthread.php?t=34649

bosch plantinum +2 plugs

I know it is off the topic, but get those plugs outta there.....they will get ate up w/ the waste spark system of the 60*'s....

go w/ regulare Delco's. They are the best.

Trust me on this one.

v-groove it!

here here on the Z06 thang!

can anyone back up this claim?? 'cause they have been in there a while and everything seems to be fine.

[grandprixgtp_91]

yes get rid of them, ive seen alot of problems with them. use stock delco plugs they work the best. and are cheap.

The problem that Bosch has acknowledged when using their Platinum plugs
in engines with waste spark ignition systems stems from the tendency of
electrode metal to get transferred depending upon the polarity (direction
of current flow) of the spark. In waste spark ignition systems, 1/2 of the
plugs always see reverse polarity sparks. Given the very narrow platinum
center electrode of the Bosch Platinums, performance will be degraded more
significantly when reverse polarity sparks will cause material to be
transferred from the large ground/outer electrode onto the narrow platinum
center electrode's exposed end surface.

Pretty convincing if you ask me. I personally run the AcDelco Rapid fire 8's in my 3100 and love them.

Just checked them after 15k of spirited driving and they still look brand new.

throw em out... trust me i work at autozone and have customers come back trying to return the plugs or swap em out for others... i had a customer put some and a honda accord and not even been able to turn his motor

a discussion from n-body.net spark plug recomendations

Like I mention in the thread . . . the electrode on the +2 and +4 Bosch plugs stick out from the ceramic only a fraction of an inch, and is very small. Unless you're running a high compression motor, carbon will build up over the electrode and will require more voltage to fire to ground. Over time as that carbon deposit grows, it absorbs more fuel which will quench the spark.

ACDelco's recommended here also . . . or Splitfire's

my car seems to run fine, but someone mentioned in another thread the bosch plugs can cause rough idle. and my car does that from time to time, but it doesn't do it all the time so i though maybe bad gas. but now i know where it is coming from.

What I've seen happen in some GM's with those plugs is the narrow center electrode disintegrates to BELOW the surface of the porcelain. So basically it just ceases to fire.

Right.

More like their shitty design just causes the platinum electrode to fall off.

DON'T BUY BOSCH SPARK PLUGS!!!

It's not a specific problem with platinums, because AC Delco platinums are in N*'s stock and run 100k+. You put bosch platinums in a N* and you'll be misfiring in 1k because all the electrodes fell off.

The "best" spark plugs out there are NGK Iridiums. The iridium metal allows a smaller electrode for more heat to transfer to the kernel. You'll see smoother idle and no spark blowout if you're running nitrous/boost. Just be careful not to put any pressure on the electrode when you gap them. And at $7 a plug they're not for everyone.

Hmmm . . . one better . . . ACDelco irridiums. They're re-boxed NGK's with ACD numbers on them, and they tend to run about $3 cheaper

Really odd incident I had with some Bosch plugs was in a '96 Blazer . . . for some odd reason, the Bosch number for the application had rolled threads as compared to the sharp threads used by ACD, and after 300 miles, 4:6 cylinders wouldn't hold compression . . . seriously

put in a new set of ACD's and she ran perfect
