Hi, I have 2004 wrx with an ecutek remap k&n apollo filter turbo back exhaust & walbro fuel pump. I seem to get a very slight hesitation when i wot in 2nd & 3rd i have changed the plugs (ngk6b) but left them pre gapped at 0.8mm should i have set them to 0.7mm.

Thanks for any advice

 

iv jst asked the same question 2day as putting 7's in mine / im sure gap should be 0.65-0.7 , if i get a responce from the tek guys il pass it on ... but (dont quote me ) im sure 0.8 is to much hivis , regards

 

As above 0.65/7 seems to work well

 

Cheers guys will re gap tomorrow

 

Just done mine on my 2002 bug eye but still got the hesitation done a diagnostic check and my Cam sensor is playing up maybe worth checking it on yours as well bud
