has anyone fitted these and noticed a reduction in inlet temp?

I know they say every little helps but is it worth it for say 2 bhp

cheers

 

I had these fitted to mine, they are supposed to give a better fuel/air mix as well as avoid heat soak.

On another plus, it is so easy to remove/refit induction pipe.

 

was there a noticable difference when adding the mod? I know its only £75 but you have to buy 2 gaskets also postage so goes to £100.

Just want to see if anyone has seen the diff before part with money

 

I made my own,only cost £15,and have enough material left to make two more.Also made the header tank spacers too. All you need is a sheet of tufnol,a abro file,and if you have it a dremel to smooth it out helps.
Before the mod ws done,the inlet was quite hot after a run,hard to put your hand on it for any time.Now,you can lean on it fine,much cooler.
