Has anyone used either the Mugen or Skunk 2 radiator caps? Notice any real benefit? I had the Mugen high pressure radiator cap on my 00 Civic Si and it did lower the temp but I have no idea if it would be worth buying for my 03 RSX-S. Im in So Cal and it will be very hot summer and i have just...

Hey guys, only reason I'm posting this question is because after some search I couldn't really find a definitive answer; is there any real benefit to replacing the rear LCA's besides bling points? I know the definite benefit to a rear sway bar, but I'm wondering if I should pair this with a LCA...

have a 05 stock type s with intake. No plans to mod the car but found a relatively good deal on a new megan test pipe. Should I buy it? Any pro's or con's?? One pro is getting rid of that nasty cat smell at vTec!

Hey. I just got an RSX base and everyone has been telling me to get intake and exhaust. I just want to know the pros and cons of having it.

New guy here... I have a CTSC TSX with a Stage 2 Snow Performance kit, which comes with the boost-activated injection controller. I was using it to balance out my A/F ratios when running a 3.2" pulley since I only had a Hondata reflash mapped for 5psi (TSXs didn't have a K-Pro option until...

I plan on running 16" wheels next year, trying to go for something a little different. :D But I was wondering is there really advantage for the 16x8 vs 16x7? There is quite a difference in price between the two as well. I know you can run wider tires but I only plan on running 225-50R16 tires...

Are there still benefits for me to switch over to Synthetic Oil at ~74,000 miles? I've always used the regular oil, serviced by myself or Honda. I've contemplated switching to Synth in the past when the car was a baby but never ended up doing it. Is it still worth it to do it today?

Hey everyone, Here's a really dumb question, but hoping to get some answers. What are the benefits of lowering springs? (other than the obvious one, looks) It should improve handling, but by how much? Much better than stock? Thanks,

What are the benefits of having a k20/k24 block sleeved? Will I be able to safely rev higher with a sleeved k24 block vs a stock k24 block if both blocks had aftermarket pistons & rods?

What are the benefits of getting the Profec-e01 other then just having a boost controller? I plan on keeping the boost at the 6-7 psi but what else can the Profec-e01 do for me? I read about it on GReddy's site and only one thing really got my eye. It said it can smooth out the boost curve...

What's funny is I drove my Civic Si with a CEL for months and I ran faster at the strip than I did before I added my powercore race converter straight pipe - I think what people are listening to is a scare tactic that is thought out by environmentalists and agreed to with car manufacturers due...

can anybody explain to me the benefits of sportshift?
