    fitted my new tophat, boost pipe and 2.2 airbox

    well i did some shopping off 'loaded' got myself a nice tophat and boost pipe with map sensor fitment,(still need to modify a pipe to straighten it up) nice mod tho, looks great too. easy fit. i also bought a 2.2 airbox off 'huey' (cheers mate ) but what can i say, the tophat mod made a huge difference, i expected a small gain, but i am feel a bit more than a small gain! lol. lots of low down grunt.
    i also found out today my spark plugs are shot. i had NGK iridium fitted with my stage 2, i have done 20k with them and the electrodes/ends are like pin thickness! really worn away. so i need some plugs now.
    here are some pics, also in pic you will see i broke something that come off the breather near FPR, i dont know what it is or what it does?? i have had to put a temp pipe in for now. is it a filter of some sort?

    Looking good mate very similar to mine

    That thing you have snapped is a one way valve. You can pick a new one up for a couple of quid - worth replacing when you can.

    I noticed a difference too when i fitted the top hat revs nice and freely.

    If that's just a open pipe you've put in place of the one way valve then you're going to cause your self alot of problems.

    When the engine is under boost pressure then the sump will also be pressurised, means all your sump gaskets will start too leak and you'll also restrict the flow of oil back from the turbo.

    Just disconnect it and plug both end's until you get a 1 way valve.

    I had all these problems on mine because the previous owner did this
