    Alfa 147, 156 & GT
    Dear All. Could you please tell me what Twin Spark means and why it's supposed to be so good! Thanks Liebling
  2. Twin Spark Engine Note

    Alfa GTV & 916 Spider
    Just wondering how Alfa manage to make an in line 4 engine that sounds so wonderful when revved. Every other in-line 4 I have had sounds crap by comparison. Is it to do with the firing of the extra spark plugs making it sound more like a V10? I haven't even heard the V6 and I believe that...
  3. Spark Plug Stupid Question Time

    Alfa 155
    Hello again everyone. This may be a daft question but....... I haven't looked at the plugs in my engine yet, but I assume the spark gaps can be adjusted ??? If this is the case, what should the gaps be ??? I have a 1.8 litre 8 valve from '94 By the way, all my posts before the site went down...
  4. Spark Plug Leads ?

    Alfa 155
    Hi guys, My car not been running too well lately. it was sort of misfiring and cutting out when I left it idle. I opened up the bonnet on evening (it was dark), and saw little sparks flashing around the bolts on the cover over the spark plugs. This lead me to believe that I was having a problem...

  6. Brisk Spark Plugs

    Alfa 155
    Has anyone out there tried Brisk spark plugs on their 155 TS 16V engines? How are the power outputs after that? I saw the chart which showed an 8% power gain on a E36 BMW 318i. Wonder what it would be like for ours.
  7. More Spark Plugs !! (sorry)

    Alfa 155
    Hi Guys, I've been reading all the posts on spark plugs. Apart from the NGK plugs, people keep refering to Bosch plugs that can be bought a lot cheaper. Has anyone actually used the plugs, and if so what models are they ? Also are they long life (50K) or just normal plugs (10 - 20K) ? I...

  9. Spark Plugs

    Alfa 145 & 146
    Hi, My 145 cloverleaf will shortly be reaching its 5th Birthday. It's got 45,000 miles on the clock and the variator gone so I'll get the belts changed on the next service. Question is should I get the spark plugs replaced as well? I'm tempted to keep them in for another year to keep the...
  10. Twin Spark Clatter

    Alfa 145 & 146
    We've recently bought a '97 145 Cloverleaf. We bought it off my father(who's just got a 2.0 147). I must admit to having a soft spot for the stunning design of the 145 as this is our third. I follows a 1.6Boxer and a 1.8TS. The car is absolutely fantastic in every way but I have noticed the...

  12. Twin Spark Woe

    Alfa 145 & 146
    I have discovered that the Cam Cover on my 145 Cloverleaf is cracked around the top right fixing bolt. The thing is that I have just had the cam belts replaced. Does the cam cover have to come off to replace the drive belts, or is my garage just going to say "it wasn't us". Any advice would be...
  13. Twin Spark Overhaul

    General Alfa Discussion
    Hi In next months (Feb 2002)Car Mechanic Mag, there is going to be an article entitled 'ALFA ROMEO TWIN-SPARK OVERHAUL'. It looks like it will be a 16v as that's what's picture awaiting dismantling. Could be useful for timing belt & variator twiddlers. Its out on 18 Jan
  14. 16v Spark plug Replacements

    Alfa 155
    Hi Jorge, Sorry took so long getting back but havn't been near the authorised dealer up until now. Thought I'd post as may be of help to other Alfisti! Unfortunately Bosch do not list a platinum plug for 2 litre valve like yours. But they do manufacture the super plus 4 which I think will...
  15. Spark Plugs/ Coil Packs

    Alfa 155
    I thought i'd give my Alfa the once over before the winter sets in, a bit of redex treatment, new blood etc. I took the spark plugs out to pour the redex direct into each cylinder, jobs a good one. When i was putting the last spark plug back......."snap" **** i thought what have i done. I only...

    General Alfa Discussion
    Does anyone know what changes Alfa made when they made the 2001 year models Eoro 3 emissions compliant? Pete (using Catherines profile because I haven`t got my own yet!)
  17. Cam belt/Cam variator. Twin Spark engine.

    General Alfa Discussion
    Hi all. Has anyone ever taken on the job of replacing their Alfa engine's cam belt and cam variator ? This would also include replacing any tensioners et cetera. Apparently there is a document on the web that details replacing the cam variator but I've been unable to find it. I've rebuilt...

    hi; Any performance spark plug recommendations for a 155 Q4? Spark Wires too? ------------------
  19. End of the Twin Spark?

    Alfa 155
    According to my local AR dealer, the TS is being axed later this year in favour of a direct injection engine. Apparently, it is getting harder to get the TS engines to comply with EU emission regulations without dropping power. Has anyone else heard about this? First the boxer, then a GM V6...
