I ran the 97t plug in my B5 after I broke it in then switched to a p3 and really couldnt tell one bit of difference.. I ran the 2050 and also the jp3 and I thought the jp3 was a little better. both had good bottom but the jp3 had a little better top, both had the same mileage. as far as clutch well...thats up to you the motor has a lot of grunt and should be great in truggy.
