Talking WOW!!! what a difference that made

Recently de-snorkeled my boxster and did the exhaust mod.

Today i fitted a K&N air filter and for the first time since i've had her i put some fuel in her, i put in super unleaded which is 97RON and put in the fuel tank some Redex fuel system cleaner.

OMG!!!!! what a difference now to when i first got her two weeks ago, theres a huge difference in acceleration and throttle response.

I would definately recommend this to anyone who hasnt already done it.

Anyway just thought i would share my excitement :-)

Absolutely not at all.

For a start a performance filter and higher RON fuel is going to make a difference

Im quite a sceptic when it comes to free mods but im telling you its loads better

We get unleaded which is 95 or super unleaded at 97 so im guessing what was in there before when I got it was 95 hence the big improvement

I see. High flow filter helps, too. Just be careful if it’s oiled as the MAF easily fouls.

That filter did nothing to add any performance. All the mods you made wont make any changes to the way the car runs or drives, including the exhaust. Placebo effect completely.

As I stated in addition if it is an oil type air filter- as microscopic oil coated dirt particles begin to stick to the MAF it(the MAF) will give false readings and the engine will begin to run rich. And progressively get worse.

OK no probs, your entitled to your opinions but I've been driving mine for the last two weeks, you guys haven't. I've been driving and modding cars for over 30 years, believe me I know when a car feels different

Cheers

Don't fret over the negative-nellies: they're everywhere.
Some people will try to diminish everything and anything, unless it's theirs. It's sad, really.

The point behind modifying a vehicle is to make it more to your own satisfaction. So nobody else's opinion needs to matter.

I bet the sound alone is worth the mods you've made. And for some of us, simply changing it from what every other stuff-shirt has, is a worthy end-goal.

I desnorkeled mine a couple weeks ago when a friend and I were detailing our cars. Don't know if it added any perceived performance gains but it does sound throatier and seems to have a quicker response.

I feel your pain and heard the "placebo effect" on here so many times. You're correct, you know your car and you know when you did something if it benefited it's performance. I've had my 2003 S since 2013 and it's my daily driver, matter of fact it's the only vehicle I own. So I know when I make a change and I feel a performance difference, good or bad, it's not a "placebo effect". Been modding cars many years myself, just a little over 30 years at that. Enjoy your performance gains!

Thanks for the positive guys. They are quick to jump in with the negativity but if they read it properly they would have seen not once have I quoted bhp/torque gains just quicker acceleration and better throttle response. Then in another coment said it was probably because of the higher rated fuel and performance filter.

This also is my daily driver so yeah I see differences when driving her.

Cheers guys :-)

Agree on not over oiling the K&N filter. Makes a mess of the TB and MAF. Previous owner did that to mine. I had to clean it all out and replace the MAF. That fixed CEL and performance issues. It works great now!

Yeah, K&N isn’t the best idea for these cars. I’m with the rest. Mine had one and the intake was a mess. Doesn’t take much to over oil them. I pulled mine, put in a stock Porsche filter and never looked back. Car still sounds great.

Louder exhaust and intake noises make your car feel much faster.

But the important part is that you are happy with your mods.

Ill say the same to you as I said to the others saying the same thing, go back and read my comments in full before you feel the need to comment and you might have noticed I never quoted any BHP/TORQUE gains and the difference has more than likely come from the higher octane fuel
