Default GruvenParts

Just recieved my 1" arms from www.gruvenparts.com and replaced the broken arm on the RH (as you look at it) inlet vacum pod. Easy to do, after taking off the engine cover. Just pushfit the old off & on with the new, all done by hand. Took her for a spin and noiced quite a difference on my now 190K 2002 S8. Between 2,000rpm & 4,000 there is definately more torque and so the gbox does not need to kickdown as much. All in all a major performance improvement for £80. I'll see if it improves the 23.6 mpg average and post any changes. Well worth checking out if yours have snapped as most do and go undetected.

do the 3.7 40V V8's have these arms as well, or are they only the domain of the 4.2?. At 175,000 miles should I be checking.

I expect it does - just pull the top engine cover off and they're visible on the front of the engine - couple of bellows is all it is

You may even be able to use the 2" arms advertised recently?

Yes they do have them, and as Adrian suggests they are longer than the S8 ones, but you won't be able to use the 2" arms advertised recently because I have already acquired them!

I've averaged 14.9mpg overall since I started making a note of fuel fills last March.....

Tank average ranges from 12 to 20.2mpg - that's calculated average, not DIS lies!

At least you are not paying US$7.56 per US Gallon.

I have a set of Gruvenparts S8 1" arms available if anyone is interested, see For Sale section.

Brand new, not even opened.

I checked mine today, the plastic ones are fine and still in one piece. I also checked their operation, and both seem to move correctly so it seems I am all good.
